  Fresh Air
Reviewed by: Diane Morgan-Ogle from Foster City, California

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.
  No more arguments
Reviewed by: Allergy Sufferer from Castle Pines, Colorado

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.

Customer Q & A

Q1: What other kind of allergens does this screen filter out? The description doesn't specfy! I'd like to know if it can filter out pet dander that I don't want floating in from outside.

A: Some, but small dander in particular, like cat dander, could and likely would potentially pass through. It's a tough balance between filtering but not choking off airflow to the point where no air passes through. Pollens, dust, mold and fungi spores as well as visible particle. Hope that helps!

Q2: 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

A: Good question! The overall maximum depth of any of these filters is going to be about 1 3/8".

Q3: Will the screens block out fungal spores ? What is delivery price to uk?

A: The size of fungal spores can vary pretty widely. From 1-100 microns, the sizes can make filtration difficult. For pollen grains with a size of 14-18 microns, the filters tested out with 98.1% efficacy by an independent lab. So while I would say they trap most fungal spores, simply due to the size of the particles, they cannot trap all. While something like an EU rated HEPA filter H13 would be more effective airflow through the filter would be virtually non existent. In terms of shipping, it's going to be cost prohibitive to ship to the UK. For a pair of filters, the cost would likely run around $100 USD to the UK. That would vary based on a specific post code I chose one at random and quantity. Hope that helps.

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 catridge 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.
