My rating 5 star rating only refers to the quality of the filter itself. The filter seems good quality for the great price. However, the filter is around a quarter to half inch larger than my old 28 X 30 filter. I had to cram the filter my furnace, but it will suffice. If you have a Carrier geothermal unit, take note, and measure your filter first. I would buy this filter again because it's a great price but will probably go back to my old filter that properly fits my furnace. Luckily, I didn't buy very many filters.
Filters are not correctly sized. I have purchased filters from multiple companies and this is the first time they were off enough that they almost fall out when unit is off. Too bad I bought 12. I think the pandemic has resulted in fewer suppliers of this size filter but I hope more are out there when I need to order again.
Ive had about 3 resources for my HVAC filters, but the last 2-3 years have settled on FilterBuy. Ive moved up, this order, to Merv 11 and have not installed them yet. But Im looking for good results.FilterBuy processes orders and ships quickly. Ive had orders arrive in 3 days on some occasions. Theyve given me no reason not to use them for my 5 properties.
Could not use these filters because the a/c has a fixed width filter holder. Two MERV 9 filters fit but the two MERV 11s you sent were a 1/4 inch too wide each.
I feel OCD to mention it, but I found it disturbing that my side by side 2 in filters had vertical pleats in one and horizontal pleats in the other. I doing see that it makes any difference though. I am hoping I will have nothing to think about when my subscription brings me two new Merv 11s in 3 months.
