This was my first purchase
on March 8, 2021
Posted by: Anonymous
This was my first purchase from You. Honestly, I was skeptical at first, but after studying your website and what you offer, I was intrigued.Then I did my price comparisons. You offered a higher Merv rated filter for a lower price than my usual Big Box Store offered for a lower Merv rated filter.I was pretty convinced your company was something I needed to try for my rental properties. I was impressed when I opened the boxes. The first thing that caught my attention was the back side of the filters. Ive never seen that gauge of support wire on the pleats of a filter. That made me smile. Then I noticed the simple cardboard frame. While its not usually something a person would pay attention too, I was impressed at the structure and guage of that as well.It was so much better than the filters I have purchased for years that are basically framed with a cardboard as thick as printer paper. I want to thank you guys!You are now my only place for furnace/AC filters.

Low cost small filter
on March 8, 2021

I found these filters to be the smallest physical shape of any purchased. They claim to be MERV 13 but look like MERV 8. The low cost attracted me to buy but since they are much smaller than the 20x24 I needed, they move every time the furnace turns on. I will not buy again

So convenient and reasonably priced. Ordered 1 years worth of filters and now can easily swap when needed. Filter was made well and fit perfectly. Will buy again!

It looked like a ordinary furnace filter to me, I would have expected a different type of filter, more in line like a hepa filter that was more densly configurate

Fits perfectly and is durable and well constructed. My filters can be hard to find because of odd sizing but these are perfect. I will definitely be reordering!

The filters seem to be
on March 5, 2021

The filters seem to be well constructed. The dimensions of the filters leave a half inch gap on 2 adjacent sides (length and width) as the stated dimensions are not the actual dimensions. To remedy this problem, a 3/4 inch wide by 1/2 inch thick weather stripping with a self-adhesive side is applied to these two sides. This adjustment makes the fit snug as it should be. All the returning air is then filtered without bypassing the filter through the gap. When the used filter is changed out, the weather stripping is gently removed from the used filter and then reinstalled to the new one. Works great.
