NQ Clarifier HEPA Air Purifiers

The NQ Clarifier HEPA air purifier is in a class by itself. Long a leader in high class filtration for some of the most sensitive commercial settings, like pharmaceutical labs, hospitals and a variety of industrial settings, NQ has taken the best features that works in those settings and turned it into a heavy-duty residential, HEPA air purifier. NQ Air Purifiers are Made in the USAWith its five-stage, hospital-grade filtration process, it absorbs a wider spectrum of allergens, and gases while neutralizing more viruses and bacteria than most other air purifier we offer.

As a step above the standard NQ Clarifier, the NQ Clarifier Medical UV air purifier uses the most advanced mobile isolation room technology available, including four, powerful UV-C lamps to destroy the most pathogens, bacteria, and viruses. The NQ Medical features rugged, durable construction and is built for use residential or commercial settings, ideal for people with compromised immune systems. Both NQ HEPA air purifiers are excellent choices for MCS sufferers as well as those with medical conditions that require first rate air filtration.

    5. In the final stage, a carbon post-filter removes excess contaminants.

This is the product I wanted - not the one I got..
So I really don't know how well it works. I had very allergic friends coming to stay for a couple of nights when I ordered this and unknown to Achoo, it was out of stock. When I realized too much time had passed and my friends were due in just a few days I contacted Achoo. Their customer service team is great and when they realized what had happened they jumped right on it and offered to ship a different even more expensive unit instead - that they felt was better than the one I had ordered. I wanted this NQ Clarifier because along with its other features, it also has UV lighting and a charcoal filter. The one I received after my friends had left has neither. The even more expensive Health Pro which they substituted at no additional cost seems to run OK, but I who also have numerous allergies can tell no difference in the air quality in my home. For no perceived benefit, I have spent an obscene amount of money for someone trying to exist on Social Security. But I repeat - their customer service people are truly great!

I can finally sleep
Every summer my nose is all plugged up at night making it hard to breathe without taking allergy medications. After I put the NQ Clarifier in my room, my nose is clear so I no longer need to take any medications.

I can see my family again...
With two cats and a dog, I was unable to have a very allergic family to my house. After gettgin my NQ Clarifier I invited the family and all were amazed that they did not feel sick when they left. Thanks! Now I have to do the dishes :)

NQ Clarifier UV Air Purifier Reviews

NQ Clarifier Air Purifier

The NQ Clarifier's odor stopping ability absolutely blew me away. We purchased the unit to help in the downstairs portion of our home, where our two cats reside. We had a problem with a musty, cat urine smell in our laundry room, so we decided to give the NQ Clarifier a try. Almost instantly we were amazed by the lack of smell. We are very pleased with the machine and we are considering putting another one in our bedroom.

What I like about the NQ Clarifier
  • Filtration - The pre-filter traps particles 10 microns and larger. Next, 15 lbs. of activated carbon adsorb odors, VOC's and other chemical pollutants. After this, a HEPA filter captures 99.97% of particles 0.3 microns and larger, and finally a post-filter with impregnated, active carbon traps any remaining contaminants. UV bulbs emit ultraviolet light to irradiate pathogens, germs and other microorganisms.
  • Dual UV Bulbs - NQ Clarifier Hospital Grade Air PurifierUV Light - If pathogens are a concern, the NQ is ideal in that the ultraviolet light emitted by the bulbs of this unit disrupt or destroy even the smallest microorganisms. Simple HEPA filtration systems alone may trap them, but they will still be alive in the filter. NQ is the only UV system that destroys pathogens in a single pass. Other air purifiers actually require multiple passes through their UV lights to destroy microorganisms.
  • Industrial strength - from the housing to the filters, the NQ is a heavy duty air purifier. Their history as a company has mainly been in the commercial market and highly specialized filtration for some of the most sensitive areas, and with the Clarifier, they have taken years of experience and rolled it into this unit.
  • Separate filters - for cases like ours, the carbon filters does most of the work. Being able to replace it without having to replace all of the filtration components allows us to focus on what we need most while reducing overall maintenance costs.
  • Casters - With larger steel units like the NQ, casters is a must-have to easily move the unit from room to room
  • Relatively inexpensive to keep the filters changed and up to date. The cost is comparable to that of other air purifiers with similar filtration capabilities.
  • Broad range of filtration - For us the odor removal was key, but with UV bulbs and five stage filtration, the NQ cleans up more than just odors. From chemicals and pathogens to dust mites, pollen, pet dander, and smoke, the NQ is up to the task.
  • Air Flow - The NQ has a powerful motor and sealed system design that allows it to draw in dirty air through the bottom-sides, clean it, then vent the purified air through the top. This design allows for a more concentrated push of cleaned air out and away from the machine to improve overall room circulation and speed the air purifying process.
  • Made in the U.S.A. - While the majority of appliances are now made overseas, NQ has been proudly manufacturing air purifiers in Connecticut for nearly 2 decades. Constructed of American produced steel, all components, except the blower (which is German made), are made here in the U.S.
What I do not like about the NQ Clarifier
  • Filter change can be a little cumbersome. With heavier duty air purifiers this is often the case. Just REMEMBER, the screw(s) that keep the filter in place, that are located on the very bottom plate, once they are removed you do NOT need to use them again. They are only installed so the filter stays in place during shipping.
  • Has a very industrial/clinical aesthetic to it, so if appearances aren't a major concern but rock-solid filtration is, this shouldn't be a problem.
As a residential air purifier, the NQ is ideal for those who have serious health problems and concerns with a broad range of particle pollution as well as pathogens and chemicals. NQ has a long history of successfully meeting commercial and residential air filtration needs. Though not the most stylish air purifier, the NQ offers some of the best filtration available for those who need it most.

The NQ Clarifier Medical offers the same great features of the standard NQ Clarifier with the exception that instead of 2 UV Bulbs, the Medical has 4 which doubles the dosage of UV that pathogens and germs are subjected to. Both units are well suited for MCS patients and those who have compromised immune systems.

Product Questions

Can the Nq clarifier get rid of polyurethane odor. Just had my floors done and the smell is sickening. Please respond asap?
1. What size area will be protected? 2. What if the area is divided into 2 rooms with an open door between them? And 3. What happens to the trapped mold spores? Don&#39t they get free when you don&#39t run the machine or when changing the filter?
