[This review was collected as part of a promotion.] I only buy Filtrete filters for my A/C system. It helps me make it through the tough cedar fever episodes we have in Texas. Pet dander, mold, mildew, super fine particles these filtration systems will keep you and your A/C system healthy.

[This review was collected as part of a promotion.] I have tried many cheaper brand filters and you get what you pay for. These Filtrete™ Ultra Allergen Bacteria and Virus are worth every dollar you spend on them. These trap so much more dust than any other filter out there. Stick with the best quality when you care about your air quality.

14x14 is what I always use but the new ones I bought today are 1/4 inch both ways too big and I cant push it into filter holder. I only use this brand and have never had this happen before. I always give top rating but unless you rectify this made too big for 14x14, I will withhold changing my rating to see how you fix this.

I've purchased this item several times. Overall I. Stified with its performance The only negative is, the filter turns black (some of them, not all) after about 3 weeks. No smokers in the house. Minimal fried foods, we seldom use candles. My Ac guy said it could be activated charcoal but the package didn't say that. What causes this?

[This review was collected as part of a promotion.] This filter is great. It traps germs, bacteria and allergens in the air. I replace it every month or as it gets dirty the more I use central air or heat causes more particles to get trapped into the filter. It is helping me have a cleaner home and better quality of air.

[This review was collected as part of a promotion.] This filter is easy to install. The construction is solid and not flimsy. You just slide it right in. Fits perfectly with my HVAC system. My whole family have allergies year round living in the south, so we need something that works, efficient, and easy to install. This meets all my criteria. This filter is supposed to capture 2x the bacteria and virus, so with all that going around, this is important to me. I feel my whole house breathes a bit better. I also like the fact it also catches cough debris and lint! Lint is something we definitely have a lot of in our house. So good so far. I will continue to use this product.

[This review was collected as part of a promotion.] This is an excellent filter. There are less expensive filters out there but you get what you pay for. I stopped buying cheap filters years ago. They just don't as good of a job. These are high quality and very effective. Filtrete is a name with an excellent reputation and I would trust most any product with their name on it. I would recommend these to anyone looking for a highly effective filter allergens.
