Good value, had in my size without going to a hardware store. Very good filtration, but (and a good but) you have to replace the filters about once a month with the effectiveness of filtration.

Great product. It does what it says it's supposed to do. I change them every 3 months. I had my furnace looked up and they said it's one of the cleanest they've seen in a long time.

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.

Since I have terrible allergies, I appreciate the utmost filtration of the air inside my home. These help achieve lower pollen count inside my home, therefore improving my quality of life.

Just in time for the start of our spring allergy season as I clean the tree pollen off of the car. I typically use the dust grade until the allergy season arrives. These are an excellent upgrade to capture finer allergens.

I love these filters. I can feel very confident knowing that all pollutants and contaminants are being filtered out. The added bonus I wasn't expecting was having less dust in my home.

'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.

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

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.

These filters cut dust and allergens down immensely in our home. The down side is they restrict the movement of air thus making the central air unit work harder.
