[This review was collected as part of a promotion.] After having the Filtrete Ultra Allergen Bacteria and Virus filter in use I have defiantly noticed a difference in the air quality. it seems to be getting all the nasties and odors out of the air! It is well marked for installing and went it well.

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.] 3M makes some of the best filters I have used in my HVAC. The construction feels solid and the fit is always perfect. When I change them, at the recommended date, they are visibly dirty and I can tell they did their job.

[This review was collected as part of a promotion.] I got these filters because: -dogs -kids with mild allergies -changing filters regularly helps your heating/cooling system work more efficiently - I trust 3M Filtrete products -cold season is upon us and these filters have amazing bacterial and viral filtering capabilities. easy to install these are sturdy and fit my furnace perfectly. i noticed. reduction in air flow noise immediately as well as less dust on the furniture. Because my kids have inhalation allergies it is critical that we keep our home air as clean and filtered as possible and these do the job efficiently and effectively.

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.

[This review was collected as part of a promotion.] I really like the Filtrete™ Ultra Allergen Bacteria and Virus air filter. It makes me happy knowing that I am providing my family an additional layer of protection from Allergens, illness, and all-around yucky air. It was easy to install and the material is very thick and durable.

[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.] 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.

[This review was collected as part of a promotion.] I can’t say enough good about this filter. Since using it I’ve noticed a difference in my allergies and quality of air. I feel like I can breathe better and don’t wake up congested as I usually do. I know it’s working for my air purifiers that I keep running throughout my house show that my air quality has improved. These are definitely my new go to filter going forward. I definitely recommend!
