H2O 4 CPAPIon Distilled Water System for CPAP or BiPAP Humidifier Water Chamber | CPAP Supplies & Accessories for Sleep Apnea | Removes Harmful Calcium & Minerals from Tap Water (2 Filters)

Works great

This type ,of filtration will only show in the long run. If the, CPAP unit lasts then you’ll know whether the filters did what most they were intended for.

Filters work great, fast shipping!

Only received one in the shipment an had to use it instead of returning since my old one was expired. Not only that issue, I opened the cellophane wrapping and it was dusty and had a human hair in the wrapping. I wish I had taken a picture for proof. The one filter didn't seem to be used so it got installed and is working properly.

I paid for the package of 2 filters. Only received 1 filter. A sticker on the baggie states 2 filters, but only one can fit in this small bag. I tried calling the H2O CPAP company at 3:30 pm MDT but a phone message said their offices were closed. Let's see if they call back.

The filters do a wonderful job, but........ the seller sent one filter even though the description is for 2."Thanks! You dooped me. 👍🏽 Never again! "

I was supposed to receive two filters but only received one.

Easy to install and totally essential replacement filter for you H20 CPAP Water Filter Pitcher. Judging from the lack of any buildup in my CPAP reservoir, these certainly seem to be effectively filtering out the unwanted minerals from the water.
