[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.

[This review was collected as part of a promotion.] Filtrete filters have always worked wonderfully for my air conditioner. They are very well made, easy to install, and seem to pull monstrous amounts of dirt from the air. Filtrete air conditioning filters have always fit perfectly and always stay in place. I love the fact that it pulls all the very small particles in the air to make my home a much healthier environment for my family.

Great quality and efficient for sure.

[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 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 can't really say this filter works any differently from the Filtrete filters with a lower allergen protection. But I can say I haven't noticed any more dust in the air than with my old filter. It would be pretty hard to tell if there was actually less bacteria in the air. The filter is of good quality though just not sure the extra money for the Allergen Bacteria reducer rely does any more than the ones without that.

[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!

[This review was collected as part of a promotion.] This is just a furnace filter. But it's really good quality and fit perfectly into my furnace cabinet. I'm not sure how I'll be able to know it works well other than waiting for a month or two to pass and understand if it works. I would think if it shows up dirty then it works!
