[This review was collected as part of a promotion.] We have used these filters in our central AC/heating system for years, with total satisfaction. We have confidence that the air is being filtered quite well - and that our use of these filters is helping to keep our home cleaner and our family healthier. We highly recommend this product!!!

[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 bought this three months ago, it catches the dust great and I was getting shocked Everytime I touched anything in my house, since I bought this brand three months ago I haven't gotten shock one time , I love this air filter and I've use plenty of others they don't match up to this one.

[This review was collected as part of a promotion.] We bought our house a year ago and have been using this filter the whole time. We have replaced them every three months and they work really well. I've noticed my spring allergies weren't as bad as normal either!

[This review was collected as part of a promotion.] This is a great air filter that works well and is widely available. It's not my first choice only because it is a bit more expensive than other brands and rarely on sale. but all in all it is a great product.

[This review was collected as part of a promotion.] I love that I never know it's there. My house is always allergen free without worry and I have never had a problem in the 10+ years I have been using them. I live just across the lake from a farm and there is so much dust and pete dirt but not in my house.

[This review was collected as part of a promotion.] I always use the Filtrete filters in our house to combat the Texas dust and pollen seasons. Keeps our family clear during the allergy season. The price is worth what this filter does for our house.

[This review was collected as part of a promotion.] I was getting 9 allergy shots per week due to my severe allergies. My physician told me to purchase allergy defense filters for my home and to be sure to change them every 2 months. I did my research and found that Filtrete Allergen Defense filters are the best to help with allergy sufferers. You can look at the picture that I attached to see how dirty mine get after just 2 months. These filters are definitely the best!

I have always used Filtrete air filters as I think they are better quality than most of the others sold so am willing to pay a little more for them...I usually buy mine at big box store, but when I saw them on sale at Sam's with free shipping, I ordered them immediately! These are also a higher filtration level than what I usually buy which is good since I have pets and dust... I change my filters every 3-4 months, so I like the 4 pack! Think it came out to about $8 a filter.....Highly recommend!

[This review was collected as part of a promotion.] I've been purchasing these filters for years. They do work for allergens. I replace mine every 2 months versus every 3. I don't know if that makes a difference or not, but my allergy to dust is so significant, I don't want to push it out 3 months.
