Simply by MervFilters 20x20x1 MERV 8 Air Filter, 6 Pack

These filters are well made. Fit perfectly. The frame is much stronger than what you get from the brown cardboard style. So far, no problems. The HCAC sensors say air flow is good. As for dust, it does seem to gather more at the intake. The furniture is not getting as dusty in a day or three. Until I have used 1 for at least a month I cant compare it to the lighter weight, less expensive filters for longevity and longer term dust control. This filter is in between the bargain and the extremely heavy duty. The very heavy duty concern me because I am not convinced they allow good airflow. So far, this filter is not interfering with airflow. So, right now, I am happy with the filter. When I change it we will see how well the particles are in the filter, rather than going out the back and recycling dust through the home as the inexpensive ones have done. Will try to remember to update this review!

I moved into a new house and found a second vent that had a filter. It was hidden in a strange place and guess it was never changed. I changed it with these filters and instantly airflow in my new house increased. A clean filter helps the whole house out. The filters are good for the price.

Husband was excited to find these filters at such a great price. They work great.

Is there a good deal for the money and they work well

Great for the money.

These filters are a very good value, one box of filters is cheaper than one filter at Lowes or Home Depot, they beat the big box stores by a a lot. They are the same as a level 4 filter, at The Big Box store brands. At this price I would change them every 30 days. It provides the most efficiency for your Heating and Cooling system, and maximizes Air flow. A dirty filter restricts air flow causing your system to work harder and use more energy. So changing them out every 30 days is a very idea. If you live in area with a lot of dust, or you have pets, changing them every 30 days is a must. These work as well or better than the big big box stores, Ive been using them for about 6 months now and Im very pleased with the results.

These filters keep my place dust free.

Super happy with this find. They work great and the price is amazing. They filter so much out and I dont mind replacing every 6 months at this price!

These fit my furnace, which requires 2 of the 12 wide filters.

Dont last as long as name brand filters but it does the trick on a lower budget just have to change them more often
