    Safeguard Window Filters

    Do you love keeping your windows open? Now you can enjoy fresh air during the spring and pollen season, without suffering from allergy symptoms.  SafeGuard Window Filters are Made in the USA These wonderful window filters keep out dust, pollen, and other allergens, so you can breathe fresher, purer air all year long. These filters eliminate 92% of ragweed pollen and capture a variety of allergens and irritants that can wreak havoc on seasonal allergy sufferers. In addition, the coated screen keeps out rain, snow, and wind. During the spring and summer months when leaving the window open means having a furniture covered in yellow pollen, these window filters are the perfect solution to still allow your home to breathe without the mess pollen and allergens create.

    If you have already purchased a window filter, it might be time to replace the filter cartridge. So instead of having to purchase an entirely new filter, you can simple loosen two screws, remove the screen cartridge and slide a new one in! Simple and easy, it takes only a few minutes and a Phillips head screwdriver to replace. Both filters and the replacement cartridges are Made in the USA.

    Perfect filter for soot laden air
    We are not allergy sufferers but we do live in New York City where air quality can be an issue. I love the summer but hate the greasy soot that comes in the windows and falls on the sills, the countertops and the furniture - it is virtually impossible to stay on top of it and remove it. The solution? Safeguard Window Screens and Filters. The design allows air to come through and circulate while keeping the soot out of my home! Everyone who visits us asks where we bought them. Thank you for this wonderful product. Review by Brenda E / (Posted on 7/17/2015)
    love these
    So glad to have found these. Bought some a few years ago but haven't seen them & even happier to know I can replace the filters!!! Love having the fresh air without the pollen Review by MP / (Posted on 7/1/2015)
    No more arguments
    My husband and I constantly argue about open windows in our bedroom. I suffer from allergies and he doesn't, so he can't understand that I want one room in our home where we keep out allergens. He was opening our bedroom windows and I was suffering each morning. We bought the Safeguard Window Filters and now he can have his "open windows" letting in fresh cool night air, and I can sleep easy knowing my allergies won't flare up like crazy.

    falling short
    I really want these to work but they are not wide enough for my windows so they keep falling down. I chatted with someone in customer service online to see if extenders were made and was disappointed to find out that there is nothing. This may be something that you would consider It would also help with sales! Review by Carol, allergy sufferer / (Posted on 4/9/2015)
    Looking forward to pollen season
    I have heard from a reliable source that these window filters are awesome. Could not wait to try them myself. I am using them and am very pleased. If that is possible... I am looking forward to pollen season and have high hopes that my solution to open windows is at hand! Review by lifetime hayfever/allergy sufferer / (Posted on 4/9/2015)
    Works well
    Works well and fits the window great Review by George Smith / (Posted on 4/9/2015)
    Marriage Saver!
    My wife is allergic to all kinds of outdoor stuff, and insists on keeping the windows shut. I love fresh air and like to sleep with the window open. The Safeguard window filter made both of us happy. It takes about 15 seconds for me to open the window, the filter in the bottom channel, slide the two filters to fit the window width and close the window on top of the filter. There is no need to remove the screen. When we leave the house, I reverse the process so I can close and lock the window. I notice the fresh air immediately. If I want to increase the airflow, I place an inexpensive 5-inch fan on my night stand to quickly circulate the cool, clean air. And on windy nights, the baffles keep the gusts outside.

    Changed my life!
    I have never been able to sleep with the window up in the spring and fall due to the pollen and the room gets so stuffy too cool for AC to kick on. Now I sleep wonderfully and the room is nice and cool!!! Thanks for this product! Review by Allergy sufferer / (Posted on 4/9/2015)
    A MUST have!
    I could NOT live without these filters! Now I can have fresh air in my home! I have these in two sizes on all my windows. They *do* reduce air flow, but allow enough air to circulate, use a fan to increase. Also, you can leave windows open in the rain or possible rain! A "must have" for allergy sufferers.

    I can breathe again!
    I love these filters. I live close to a very heavily treed area with no a/c, so getting some cool spring air in the house, without pollen, has been a challenge! Even the portable window air conditioners allow dust and pollen to come into the house especially on a windy day. I tried making my own filters with fabric and screens to no avail. Fortunately, I discovered this system. I bought my first filters probably 7-8 years ago and just recently purchased new filters. Unfortunately, for the past several years, I didn't realize they could not be washed with water & an air filter cleaner. I also assumed new filter replacements were not going to be easy to install because of the heavily "rusted screws" from my yearly "washing." However, even though the "washed" filters kept out much of the pollen for a good number of years, the new, clean filters are sooo much better! I'd forgotten just how much clean air they allow to come in. I can breathe again! My advice..... forget washing these with water and cleaners. This time I'll vacuum the filters as directed and plan to buy filter replacements. Bottom line....these window filters, and even the price of filter replacements, have made a huge difference in my health and comfort. It's wonderful to have "fresh" air in the house again. They are well worth the price for asthma and allergy relief. And much better than taking more medication! Review by Allergy/asthma sufferer / (Posted on 4/9/2015)

    The Safeguard window filters are the best invention for those who suffer from allergies. Before I stated using the safeguard windows I would wake up with sinus headached and thanks these I can keep my windows open without the risk of feeling miserable. This are a must have for any allergy sufferer. Review by an allergy sufferer / (Posted on 4/9/2015)
    Window filters keep pollen out
    The window filters are great. Not only do they keep pollen out, they also keep out dust and dirt. Now I can sleep with the windows open and no sneezing. I highly recommend the window filters. Review by / (Posted on 4/9/2015)
    We live on a busy street. I worry about the tire dust and other nastiness the cars are kicking up. These are great. You can actual see the black dust on the other side of the filters. I know they are working to keep out more then pollen. Review by JD / (Posted on 4/9/2015)
    Great filter screens
    We live in warmer climate and spring comes early. I usually cannot be outside or open windows with regular screens because of my allergies. These adjustable Safeguard filter screens are great. I ordered Qty 2 7-inch high x 20-36" adj. One for the front of the house and one for the back to provide crossflow. We have various width windows and I found they work best with a wider window, ours our 30"closer to the max adj width of 36". Those who may be experiencing low air flow may have more narrow windows and the overlap of the left part of the screen with the right part most likely reduces the air flow significantly. I had originally placed the one in front in a more narrow window 18-20" which caused a greater overlap. If all your windows are on the narrow side though, you won't have the option to put them elsewhere and you might not get enough flow. For us, they are great, we love them, and they work perfectly. Thank you so much. Review by Serious allergy sufferer / (Posted on 4/9/2015)
    Very pleased
    I was very pleased with the first Safe Guard Window Filter I ordered so ordered 2 more--THANKS for a great product! Review by wife of very chemically sensitive husband / (Posted on 4/9/2015)
    Love my screens
    I ordered the allergy screens and got quick delivery, they work well so I can keep the windows open without the pollen coming in. Thanks, Achoo allergy. Review by Pat Hogan / (Posted on 4/9/2015)
    Fresh Air
    For years I have closed my house down for 4 long months during the spring allergy season and suffered when the temperatures fluctuated. I bought two window filters and was thrilled as they are so easy to install and better yet, remove if needed. The sizes were perfect and I've ordered two more for my sister.

    Bad Pollen..Bad, bad, bad!!
    I was looking for a way to keep the pollen out but still let the cross breezes come through. There wasn't a lot of choices out there, and when I read the specifications, I was sold.These filters fit perfectly, and keep the little creepy critters out too. Review by Gerry Soucheray / (Posted on 4/9/2015)
    Fresh Air in, allergens stay out
    Over the last few years I have purchased a total of 4 Safeguard Adjustable Window Filters to supplement my regular screens. I now have 3 7" and 1 11". I don't know what I would do without them as I am allergic to pollen, grass, trees....most everything outside. They allow me to enjoy 92% allergen-free fresh air with cross breezes throughout the home. I have told everyone I know with allergies about them. I am so glad I found them on your site. Thank you. Review by an allergy sufferer / (Posted on 4/9/2015)
    Awesome product
    I won't ever open my windows again without putting in one of these screens. They fit perfectly no matter how big or small the window is. Air plows right thru them without ever letting in the bad stuff that makes my allergies act up. Plus, the rain never gets in either. Review by Dawn / (Posted on 4/9/2015)
    Filtered screen inserts
    No assembly and very easy to use. Seem to be very a well made product as far serving the purpose it is intended for. The packaging was a recycled brown paper and I was appreciative of this since other companies that use that crumbley styrofoam are not realizing how big of a mess this causes when opening packages, so I assume that this company is environmentally aware and responsible. Review by Karen, mother of allergy sufferers / (Posted on 4/9/2015)
    Bought 3
    ...and so far they seem to do what they're supposed to do. I gave only 4 stars because after receiving them I actually saw the exact same ones elsewhere for cheaper. One of the main reasons I bought them was because they're supposed to be ok to leave in window even when it rains, but it hasn't rained yet so I don't know yet about that feature. It's good feeling to be able to have my windows open and not get all the junk from outside coming in. I have been struggling with flu-like symptoms for years and this is another of my efforts to eliminate all causes. I also use air purifier and bed coverings etc. It would be nice if I could find something like this to fit my metal security door so that I could leave my inner door open all the time. Or at least the material to make one. Review by Flu-like symtoms sufferer / (Posted on 4/9/2015)
    So far, so fantastic
    I recently bought three window filters and have used them at least 5 days in the past two weeks. I even kept the windows open at night and it was great to wake up with no puffy eyes or sore throat. My allergist has been telling me for 5 years to keep my windows closed and use the a/c, I am so allergic to the dust and pollen and susceptible to sinus infections. So, it's been great to enjoy the nice weather we've had lately. I'm incredibly happy with my purchase. Review by Dolores / (Posted on 4/9/2015)
    Allergy Sufferer Life Saver
    I had bought the 11" high window filter years ago from another source and was thrilled to find the 11" and the 7" high filters on the Achoo Allergy web site and at a good price. I feel confident that I will not wake up with headaches and sneezing with these filters in my bedroom windows blocking the majority of allergens. I'm in the process of allergy shot therapy but I am grateful to have these in my windows to help with my symptoms. Review by Midwest Allergy Sufferer / (Posted on 4/9/2015)
    Great Filtering. Lousy Airflow.
    First the positives. Extremely well made, with good hardware and seals so that it fits a window snugly. Good job filtering out dust and soot. Great at keeping rain out, so you can leave window open during rainstorms. Recommend for this function. The bad news: airflow is drastically cut. I live on the 19th Floor of a New York City co-op on the East River, with great breeze without the filter. With the filter, I would say the airflow is reduced by 70-80%. Works for me because I started with a high airflow, but it could be a problem for others. Review by Kumar / (Posted on 4/9/2015)
    Breathe easy
    I love this product. I live on the second floor of a building right above a gravel dirt parking lot. I would come home and find all the dust particles from the parking lot on my clothes, my bed, and on my kitchen table. I had to sweep twice a day just to keep my allergy from killing me not literally of course. As soon as I got this product it took me approximately 2 minutes to take it from the box and place it easily in the window. I can breathe easy now. I no longer find those large dust and gravel particles all over my apartment and clothes. The best part is that it really lets the air in and keeps everything else including rain out. It also traps other allergens. This is a must have for allergy suffers. Review by L.Thomas / (Posted on 4/9/2015)
    Soot free
    My office is on the side of the building facing a well traveled roadway. Buses stop outside my window to let passengers off on a regular basis. I could not open my window as black soot would cover everything in my office. I had serious concerns regarding my health after seeing all the black soot attached to everything. I found the Achoo Allergy Safeguard Window Filter on line and decided to try it. I have had it in my office window now for two weeks and it is working. I am getting air from outside minus the soot. This is the first time that I have actually felt safe breathing the air in my office. The product is fabulous! Thanks Achoo Allergy! Review by Safe breathing office worker / (Posted on 4/9/2015)
    Bummed in Brooklyn
    I live next to the elevated subway platform in Brooklyn. The dust and dirt thrown from the platform comes into my apartment and is like black soot. Upon moving in my boyfriend developed asthma and I developed a cough. After using the Safeguard Window Filter for a week my cough went away and there was no more black dust in the apartment. I am a huge fan and now recommend them to everyone I know who lives in similar conditions. Review by KF / (Posted on 4/9/2015)
    The Wonder Screen
    This window screen is more than just a screen, it's a life saver--literally. My boyfriend lives a few feet off a busy interstate, and the noise and car fumes and dust are indescribable----before THE screen. Now we can sleep without hearing the banging of heavy trucks, smelling the the impossible-to-breathe fumes or having dust all over our furniture. That's why we call it a life-saver (it's also a relationship saver!). Unless you have one, you can't appreciate the difference it makes!!!! Review by C. Rogers and C. Snow / (Posted on 4/9/2015)
    This window filter is the best. I can safely leave my windows open and not worry about a thing. I have ordered these for myself and several friends. They are great Review by Dorothy / (Posted on 4/9/2015)
    Keeps the house clean!
    Aloha, We live near a busy freeway in Honolulu. When I clean the screens and cabinets they are always black! We are breathing this stuff! In Hawaii every one leaves the windows open to the trade winds. Since I put the filters in there has been on black dust on the cabinets near the windows. The filters are also well made and telescope smoothly. I would recomend these for city dwellers to keep out the dust and soot. I don't really suffer from any alergies but these keep the air clean. Thanks Review by Joel Savoie / (Posted on 4/9/2015)
    Excelleant Product
    I was looking for a window screen that would keep out the rain etc. But when I found out yours also screened out harmful air born pollutants, I was surprised. I find the product is as advertised. Thanks. Review by Breathing Easier / (Posted on 4/9/2015)
    Early review
    Product seems to be constructed well. Arrived propmptly. Seems to be doing the job although only a year of use will really tell. Just what I wanted in terms of function ie. a way to let in the outside air without the pollen. Wish it were a little thinner. Review by Kappal Singh / (Posted on 4/9/2015)
    Fresh Air Despite Allergies
    With the high pollen levels, it wasn't possible to open the windows for fresh air until I purchased the Safeguard Window Filter. Although there is not the same breeze as a screen would allow, it permit a fresh air exchange. I am happy to have discovered this product. Review by Lynne / (Posted on 4/9/2015)
    True to Form!
    My wife gave our room the "pollen" test, and, it passed with flying colors! Plenty of air passage and pollen was at bay during a peak period. I ordered 2 more for the spare room. Review by Dust Fighter / (Posted on 4/9/2015)
    A great solution for people with allergies
    My wife is allergic to almost everything. These window filters do not prevent her allergy reaction 100%, but we have seen and smelled a lot less stuff coming in through our windows. Our windows faces a busy street, and we live on the first floor above the laundry room of an apartment building. You can't imagine how helpful these window filters are doing for us. Review by JT / (Posted on 4/9/2015)

    Just glad to be able to limit the amount of pollen coming in through the windows. We can keep the air flowing without the bother of pollen clean-up. Review by David D. / (Posted on 4/9/2015)
    no airflow
    filters don't let in enough air. Review by allergy sufferer / (Posted on 4/9/2015)
    window filter
    not much air passes through the filter so you don't get the same effect as an open window. However, there is some passage of fresh air that does add a fresh air dimension to the house without any breeze. Review by fresh air lover / (Posted on 4/9/2015)
    Good idea, but...
    The filter is too tight for air to pass through. While it's true water can't get through -- air can't really get through, either. On several occasions, the filters would actually get sucked into the house because of the air pressure force from the whole-house fan. You could barely feel a breeze in front of the filters (with a huge house-fan sucking air out of the house)... without the fan, there was absolutely no airflow at all. We had much better results by fashioning a 'homemade' filter using two standard anti-allergen HVAC filters duct-taped together. This is a great concept, but you get what you pay for... Review by Allergy Sufferer / (Posted on 4/9/2015)
    Keeps out city grime!
    I LOVE these window filters. This is the second one I purchased, because I noticed a SIGNIFICANT improvement in my apartment's air quality after I installed the first one. I live on a second floor apartment, street-facing, in New York City, and there was always a layer of soot on the table in front of my windows. Not anymore! These keep out rain, dirt, bugs, AND allergens, and still provide great ventilation. Review by city dweller / (Posted on 4/9/2015)

    No Pollen No View
    This screen is easy to install. I gave it a three because it is so thick it entirely blocks any view outside. It's bad enough I can't be outside during high pollen days, but really hard to not see outside. I will only use this on my back window. Review by VCD Sufferer / (Posted on 4/9/2015)

    Window Filter Reviews

    Safeguard Window Filter

    The Safeguard Window Filter are a great invention! I love keeping my windows open when the weather is nice outside, especially when I sleep. However, I suffer from seasonal allergies, and in the spring and fall when the weather is nice, the pollen is a problem. That is why I love these filters. I can leave my windows open so fresh cool air comes in, but dust and pollen stay outside.

    It was not difficult to install. I just left my regular screens in place, opened the window high enough to fit the filter, expanded the filter to the required length, and then lowered the window to hold the filter in place. The vinyl around the edges did a great job of sealing so that bugs could not get in. It even keeps out rain!

    To clean the filter, simply take it outside and vacuum it off with a HEPA vacuum cleaner. You can generally do this a couple times before having to replace the filter media catridge all together. By removing two screws on each end, you can remove the plastic end cap and pull the entire screen cartridge out and replace it with a new one. While conditions will vary greatly depending on your location and time of year, we recommend you replace the cartridge every 6 months to a year in places were pollen or allergens are not high. And during allergy season you will likely want to replace the filter cartridge every 3 months or sooner, depending on severity.

    While these filters do not allow air to flow as freely though them as a traditional screen, the upside is they do allow air to pass while keeping most rain out. The filter media and screen mesh prevents large particles as well as pollen and other allergens from entering the home. They help keep your house cool during transitional months by allowing air to pass while preventing outdoor allergens in at a time when they are at their peak. For places where pollen is heavy and coats everything in a fine yellow-green powder, Safeguard window filters allow you to keep your windows open without having to dust and vacuum up pollen every day.

    Product Questions

    Hi, I have a question about the safeguard window filter. I see the dimensions for height and width, but not for how thick it is in the middle as in, how far back it goes into the window. THanks
    Will the screens block out fungal spores ? What is delivery price to uk?
    Does it matter which side of the filter should face outside vs inside for them to work properly? If so, please describe proper positioning for best results. Thank you.
