I tried purchasing replacement filters for my EPI810 from the website. I couldn’t find one by searching the model number they have listed in the description. However, one of the replacement filters was shown as being frequently bought together with the same type of air filter I have. So I bought two, but they are too large.

I thought I was getting (2) filters for what I paid, but instead it was only (1) filter. I could have gotten the same filter (but 2 filters) on Amazon for the same price. Next time I'll follow my 1st mind.
