These were too big for my opening. I returned them.

Over priced even on sale (as all filters are).

We use this filter for several years and are very happy with it.

Great price for this package of 3 filters.

I had to pull this and put in a temporary fiberglass filter after 1 week. The airflow to the farthest rooms was poor and the rooms got too cold. The pleating looked good and the filter isn't visibly dirty. I'll stick with the Merv 7 filters.

This filter is restricting airflow. Our return air is so loud when our gas furnace is running. Also we hear a thump a few seconds after the furnace kicks off. Not sure what the deal is.

[This review was collected as part of a promotion.] I like that this filter helps asthma & allergy suffers because this is certified for these ailments. I like that this filter should be changed every 3 months. The only thing I think to improve would be to have the filter last for 4 months. This filter easy to install and remove.

[This review was collected as part of a promotion.] These filters seem to be working great. Especially since this is the time when people are getting sick. It fantastic that it helps block bacteria & viruses. These are very sturdy and very well made.

[This review was collected as part of a promotion.] I suffer from allergies so I thought I would give these a try. I'm so glad I did because these work great. Since we started using these filters my allergy symptoms have lessened. I would recommend these if you suffer from allergies like me.

[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.
