[This review was collected as part of a promotion.] We live in an apt with forced air heating. That creates a lot of dust in itself. Alll of us have allergies to something different. My son is spring trees, I am dust and my husband is all year round. We buy our own rather than use the ones the complex does. Plus, they hardly change the filters on a regular basis. I am careful as to which filter I can use for the HVAC we have. Don't want to block too much air and ruin an expensive machine. For 30 years I've used these filters without a hitch. When we got new carpeting (such as it is called) it was the thinnest cheapest I've ever seen. Carpet is supposed to shed, this one just creates dust. Thanks to the filter I had less dusting to do.

Great price, especially when they are on sale. I switched to these because we live in a new development and the dust from construction was too much for the cheaper filters. They have done a great job in removing particles from the air. I change every two months instead of the recommended three but at this price it won’t break the bank.

[This review was collected as part of a promotion.] Since I started using Filtrete anti-allergen filters in my air conditioner unit, I started sleeping much better. This is something I did not expect! These filters made a tremendous difference in reducing my allergy symptoms. I use them all the time now. I purchase my Filtrete filters, even though my apartment complex gives free generic A/C filters.

Bought these on sale $31.98 for a four pack, they are very nice high quality filters. Would recommend for anyone, but especially for those with allergies. Fit great, just check your size and buy same size as ones installed and you should have no issues.

Great price for a year's supply of a brand name furnace filters. Fit is true to size listed. Generic brand filters pale in comparison to 3M filters. Allows for unimpeded airflow while providing a high level of filtering for dust and airborne allergens.

[This review was collected as part of a promotion.] My fiancé and I just bought our first house and the sellers used a Filtrete filter in the master bedroom vent so we knew we could trust it! Plus, it filters out so many nasty things you don't want yourself or your guests breathing in.

Do not fit in furnace.

[This review was collected as part of a promotion.] We have used this filter for several years because my wife has allergies and appreciates its effectiveness. It lasts 3 months and keeps my air system clean.

[This review was collected as part of a promotion.] I started using the Allergen Defense Air Filters and have had a decrease in the allergies that I have. Love the product and will continue using this. Thanks so much.

[This review was collected as part of a promotion.] This one traps so much more allergens than any other filter I have used. We both have breathing issues so this is the only filter we will buy.
