I bought this about a month ago and I an very happy with my purchase, It has reduced the allergens in my home. I was sceptical at first but it really has reduced them, myself and my family are sneezing less, even with allergy meds we were still sneezing in our home now the filter has reduced the sneezing I'd say 15%.

[This review was collected as part of a promotion.] I have used Filtete filters for years and have found them to be the very best. I am 75 years old and these have given me cleaner air. How do I know? I have a very bad case of allergies,even to the point of having to take shots. Believe me I know when an air filter is doing the job correctly. I hope you will try these as you will thank me.

[This review was collected as part of a promotion.] We really enjoy this product. We've bought a few of them now and they work great. Only thing is, and the reason for the 4 stars, research showed us that there should be at least 18 peaks per ft. for max. efficiency, this only has 17.

Living in the dusty desert we need extra filtration. This baby scrubs the air nicely. Less dusting in our home for sure as long as we keep window opening to a minimum. Also have a large dog and 2 cats, son was having trouble with cats but after this filter he has noticeably gotten better with allergies. I do wish it was more affordable but for some reason these things are not cheap to produce! It is worth the extra price than those tissue filters that pretend to be helping air quality.

[This review was collected as part of a promotion.] Our house design puts a lot of pressure on the filter with 2 pets and 3 ppl... 2 with bad allergies. I know when it's time to change the filter because my allergies return very suddenly! HUGE difference.

[This review was collected as part of a promotion.] I have been buying the allergen defense air filter and there is no comparison to this brand and filter. i absolutely can't buy anything else. i've tried to buy cheaper filters but my allergies go crazy and i am MISERABLE with the cheap filters. i notice a HUGE difference when i use filtrete and will never switch from it. they are made of quality materials and really filter out all of the bad stuff a lot better than any other filter ive bought previously. i have MAJOR indoor allergies so this kind of filter is a must have if you suffer from any kind of indoor or outdoor allergies. it makes a difference!

[This review was collected as part of a promotion.] I have been using this filter for a long time. My whole family suffers from enviromental allergies and this helps a lot. I love to save a buck but with our air quality, I will not buy the knock-offs. Try it for yourself!

[This review was collected as part of a promotion.] We started buying Allergen Defense filters for our apartment and I am SO glad we did. Both my husband and I have allergies that were getting worse and worse. When we started using the Allergen Defense filters, our symptoms were greatly reduced. I was amazed just how much the Filtrate filter made a difference. We'll never go without this amazing filter - it truly makes a difference in our health! Thanks, Filtrate!!

[This review was collected as part of a promotion.] We have cats that come in our house and this filter does wonders for my wife's allergies. These filters last up to three months and capture dust, pet hair and other items very well. Worth every cent for cleaner, fresher air.

[This review was collected as part of a promotion.] Have used 3-M allergy filters for past three years this past summer was terrible for agitators, but with C and 3-M Micro Particle Reduction filters, did not have syptoms when indoors. Really performs as advertised.
