Good brand good product. Just wish it came in size 16x24x2

Too costly and now can only get by shipping another rip off shipping scheme by sams club by taking them out of the store and making it online only.

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.

We started buying the Filtrete 1600 Ultra Allergen because we live in an area that produces lots of pollens, and we have a dog. We can definitely see and feel the difference with using this brand series and other brands. We sneeze less, and there's less dust. Our home has a fresh smell and does not smell dusty like some other places I have been. To make things even better, they are cost efficient. I won't ever change filters as long as these are available.

[This review was collected as part of a promotion.] We were admittedly overdue to change our filter and noticed an almost IMMEDIATE difference in the air. I had been waking up with headaches recently, which have since stopped, and I attribute to allergens that had been coming through the vents from our old filters. We are extremely happy with these filters so far!

I just changed this filter for the first time and I could not believe how dirty it was! I thought the ones I had been using were doing a good job, because they hardly ever had any dust on them. I will never use anything but this filter in my furnace again. It is a good feeling knowing that the air I'm breathing in my home is so much cleaner now.

[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.] 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.

I have three 20/20/1 and one 20/30/1. Use other brands no problem with the fit on the 20/30/1. I JUST SPENT HALF HOUR BENDING THE 30/20/1 to fit. Bought 4 packs year supply.
