Good Filter for Allergies

Works great but needs frequent replacement. This filter works very well and noticeably improves air quality, but I have to replace it more than once a month. It's not a bad product at all; it just gets used up quickly where I live because we deal with heavy allergens. For anyone with serious allergy concerns, this is a solid choice, but expect to change it often to keep performance high.

Good air filter. Really absorbs much more than any of the air filters that I've used before such as the cheaper brands that you might find elsewhere. I was surprised at how much this air filter picked up in my home within 30 days . I would definitely recommend it, and I felt a difference in the air quality.

Great product!

We purchase these filters to tape onto a box fan for our bedroom. It absolutely makes a difference in not only keeping the fan very clean, but we don't have to deal with sneezing and coughing as much during allergy season. It works out very well. They usually last about 3 months. Each time we change them out, there is a lot of dust, particles and pet hair that has collected. Well worth the money to stay healthier and cleaner. It gives us piece of mind. We live near a national forest where they do controlled burning, and local neighbors burn bon fires occasionally. This filter is a lifesaver during those times, because I have asthma. This works just as well as the two air purifiers that we have in the rest of the house. Highly recommend.
