They had a hard to find size which was great. But it was only available in one filtration level. I wish it was available in the higher level as well, as we have dogs, and an old house, my wife has allergies, so every little bit helps.
The filters were poorly manufactured, with folds not evenly spaced. While in practical terms this is not important, it does not compare to the even spacing of a Honeywell filter. The depth of 3.5 inches however, does result in less filter area than the equivalent Honeywell. Overall, the cost is about on par with Honeywell filters purchased in bulk from a local store. I plan to check filtration efficiency shortly.
Excellent help and service st Filtebuy! We were 100% satisfied and would highly recommend ! We just moved into a new house and had an older model that we had trouble fitting with a filter. Filterbuy helped us locate what would be best and even made an easy exchange when we bought the wrong one.
It was easy to find the size of filter that I needed, and prices are the most inexpensive that I've found. I'm not a filter expert, so I can't comment on quality. I purchased the highest grade filter (MERV 13) available, so I'm hoping that it is as advertised.
