Still waiting to find out how to return the wrong filters and get my money back for them. Have had no response from the company

The product is great and the shipping was very fast.

I haven’t received the item. I can’t find that it’s been shipped

Product arrived promptly and in perfect condition. It works perfectly as well. It’s a great asset and I wouldn’t want to be without it.

Did not let me know the item was not in stock when the order was placed.

This company IS customer service at it's best!!! They back every product and it's parts tgat they sell, without the typical red tape other vendors give you. I had a problem with a part and they replaced it immediately, after I showed them the problem. They have awesome products and 100 percent ethical! Thank you KOIOS!!!

I never received the product. You refunded my money with no explanation.

Ordered filters. Paid with credit card. Money refunded. No explanations or recourse to my knowledge.

Love this machine. It is our second one. I use it everyday!!

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 received an e-mail saying my order was cancelled by me. I do not recall cancelling my order, and I have not received any items.

Grateful they still have the filters that I need for my air purifier. And fast delivery!

Very quick shipping. Great little machine and easy to install new filters.

Had to email and phone for defective discount code. 1st reply: It's good, must be your browser do this...FOLLOWED ALL INSTRUCTIONS, STILL DID NOT WORK. Emailed my dilemma... 2nd reply: It works fine so just apply it for refund/ rebate after purchase. FOLLOWED ALL INSTRUCTIONS, STILL DID NOT WORK. Emailed for refund in amount of discount, discount applied. HOW MUCH OF MY TIME DID THIS TAKE FOR $13.52 DISCOUNT??!!

Russell- your online chat specialist was not only a great help in questions during the ordering process but also of great assistance in the registration of the warranty. He is a credit to your organization.

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.
