The Filtrete Ultra Allergen Bacteria and Virus filter seems to be helping reduce my allergies, especially when used in combination with room air purifiers. The MERV rating of 12 is higher than I usually prefer since it can restrict airflow, but these filters make it worth having my A/C work harder throughout the day. They offer great value when purchased in a pack of four, and Filtrete is a leading brand in air filters.

They were received in good condition from the shipping company. We use these filter because I have a severe respiratory condition, These filters help keep down microscopic particles that could exacerbate my condition. In my option they are excellent filters.

I believe they work. Have the 1st of the pack we purchased in my handler now. I can't speak for the way they are supposed to remove odors, mold, dander, etc..as they say they do, but I need to replace my filters once every month as required by my property management company so I got these. With the price we paid its about $10 a month. I am good with that!

Filtrete is a very good filter. Traps the pollen this time of year. I have a dual heat pump that has different Returns and the settings. One upstairs and one downstairs in the ceiling. I also have a larger return in the Den. All work well with Filtrete filters. Rarely have to dust!

This is a quality high air flow filter. I took static pressure measurements with and without these filters and adjusted my HVAC max air flow settings for each zone to stay within a 0.5 to 0.8 range for static pressure. I installed 3 of these filters and 4 months later they are still clean and having almost no impact on air flow. These filters are far better and flow significantly more air than really cheap 3M filters. They also fit the housing tighter and seal better. I know because I had some from previous owners to compare. I gave that junk away on marketplace. These combined with a robot vacuum and mop have kept my home virtually dust free over these 4 months and they have a lot of life left. If you think these restrict your air flow too much, you need to get your HVAC settings adjusted and possibly get professional help if your ducts aren't sized properly. Air flow issues are a problem with your system, not with these high flow filters.

Filtrete filters does the job.

Long time user of this product, theu work as expected.

These filters are superior to what I normally buy. The price was good for my budget.

I like the package so I have some on hand.

I needed new filters and had been putting it off. Now I have extra.
