Fine Service, Fine product, Fine price

Great experience throughout the process. The phone assistance was clear and quick, the product was in stock but the competitor's wasn't, the price was better, and the filters arrived in time. Nice work!

Great price and quick shipping and delivery.

The price was better than anything that I could get locally. The filter was delivered in just a couple of days. Will definitely buy from Doheny's again.

Pleatco Filters

I was very happy that the filters shipped were exactly the ones I ordered. I've had other companies that despite what they advertised were not what they sent. Pricing was very reasonable too.
