I find the filters to be reasonably priced and do exactly what they say they will. Ordering and delivery is easy. The reason I gave 4 stars instead of 5 on the 'value for the money' was because the filters are slightly smaller than name brand filters and barely fit the metal frame in my furnace; i.e. because they're smaller, they can slip off that frame. So, I tape them into place (which also helps prevent airflow around the filter).

Based on my home air quality sensors it appears that these filters do a good job in helping to cleani the air. When replaced after 6 months they show significant dust and dirt that were removed from the air. I think they are a good value for the money.

I order these about twice or three times a year. Saves me time ordering online and I'm not in any hurry but I like to have enough on hand so when I do change them I have them. The price is very affordable and after having our vents cleaned last year they help tremendously.
