- Awesome product, awesome price, and unbelievably awesome and honest company!
- These filters do the trick and I am able to get more life out of them compared to others.
- Great price, looks like official filters. And was delivered quickly.
Giving 3 stars for now awaiting response from epool supply. I received the filters timely, they were a good price, I have always found quality OEM items at competitive prices with them so far. However, these filters are not as expected. They only have one band at the bottom holding the pleats together not multiple bands as shown in the picture which was an important feature for me for stability for frequent cleaning due to environmental conditions nearby. I specifically chose this product over others at lower cost due to the additional banding. The box is marked Pentair and has the correct part number. The filters are made by Pleatco which is what I expected for their replacement filters. Everything is as expected except the banding. I don’t think this was intentional. I think someone didn’t update the product photo when the spec changed somewhere along the way. However this was a selling point for me. Hope they make it right.
I was under the impression that these filters would be from the actual Pentair Name Brand, but they were not. Also, the filters were not sealed in plastic packaging as they are in the photo, which can lead to the material breaking down quicker. I bought these as spares to be stored away and without the plastic seal, I'm afraid they will not last very long in storage. They arrived relatively quickly.
These are OEM parts that were delivered quickly and at a reasonable price. I have been very pleased with ePoolSupply.
Great product and price.
Great price, looks like official Pentair filters (Pleatco). And was deliverd quickly.
As described

Very helpful video. How do you know when it's time to replace the filters? (vs just cleaning them?) How long should these filters last? Do these last longer than the aftermarket filters?
Pentair filters are stamped “Pentair” on the ends of the filters.
We have been using Pentair and Pleatco filters for 20 years.
They are always stamped on the ends of the filters.
I purchased these in April 2024.
They came in a “Pentair” box but no stamp on the ends of the filters. These are generic 420 filters.
This is a bait and switch- plain and simple.
Pentair stamped filters usually only come with the purchase of a new pump system. I confirmed this with my pool service company.
Buyer beware —what you are actually getting.
As described, genuine Pentair filters. Great service too.
Great deal on filters. Glad Pentair decided to start making these replacement filters.
These filters do the trick and I am able to get more life out of them compared to anythers I have tried.
It was a great price. I look all over the internet for a better price and couldn’t find one lower.
Thank you received in record time.
Great OEM product
