There are cheaper filters but these are of excellent quality. One of these filters lasts us about three months. We have a lot of agricultural dirt & grain dust in the area in which we live. The extra filtration qualities are worth the price.

Prior to using this filter the hardwood floor beneath our bed always became covered with lint/dust from the heat register. That's no longer the case with this filter.

Very inconsistent in size. The actual dimensions are bigger for a filter in the pack, while a different filter has correct size to fit the vent opening. Very frustrating!!

Quality product that does the job our HVac person told us a good quality filter changed monthly will extend the life of our furnace/ac. And it certainly does.

Great Filters to use, our service guy said we could go up to 3 months before changing them out with good filters. We change them every 4 - 6 weeks but knowing we could go longer using a good filter is good to know.

Comes in a pack of 4. Hard ro find size. Got tired of waiting to order elsewhere. Friend came over and easily replaced. I have asthma and know when it is time. Have ordered them before.

I've used these filters before, and they seem to work great. I've not noticed and issues with the HVAC system. Sams Club are much less expensive than most other retailers for the same filter.

I have just changed the filter so I can't say anything about the filter yet. I did have directions that were easy to follow. I had no difficulty installing the filter

'These seem to be working well this summer. I bought them as a trial from 2800 after the HVAC tech suggested an easier way for the air to flow. So far I really can’t tell a difference except it’s better on my cash flow.

Excellent whole house filters that don’t degrade under heavy air flow as others I’ve tried. A bit pricey, but worth it the peace of mind and allergen reduction.
