For optimal performance ultra fine filters should be changed regularly when they appear soiled or discolored.

DIMENSIONS: Approximately 1.75 (1-3/4) inches long by .875 (7/8) inch wide. These filters were originally manufactured with a small tab on the long edge however the tab is no longer included as it has been determined that it can cause the filters to pop out of the machine during use.

COMPATIBILITY: All PR System One REMstar CPAP Machines (PR System One REMstar SE, REMstar Plus, PR System One REMstar Pro, PR System One REMstar Auto, etc.). All PR System One BiPAP Machines (PR System One BiPAP Pro, PR System One BiPAP Auto, PR System One BiPAP ST, PR System One BiPAP AVAPS, etc.). All M-Series REMstar CPAP Machines (M-Series REMstar, M-Series REMstar Plus, M-Series REMstar Pro, M-Series REMstar Auto, etc). All M-Series BiPAP Machines (M-Series BiPAP Plus, M-Series BiPAP Pro, M-Series BiPAP Auto, etc.). All SleepEasy CPAP Machines.

USAGE: These filters are NOT compatible with older REMstar systems. Older REMstar and other Respironics System filters are available elsewhere on this site.

  • Too Thin

    Have used since product had small tab at the top. The thickness of the product was excellent. Since removing the tab, the thickness was reduced causing the need to change more than once a month. At 2.25, with 2 clients using, can get pricey for the year if insurance doesn't cover.

  • Package quantity

    I am happy with the product and the timely delivery. I would have been more satisfied if I had been able to tell that there was only one(1) filter per pack. That was not clear in the description or ordering process. I didn't how many I was getting until it arrived. Had I known ahead of time I would have ordered additional quantity.

  • fast and economic service

    I ordered the fine, or HEPA filter for my Philips CPAP and the order was here, to Montana, in just a few days. The most important factor is that our local supplier has a 300% markup above the Direct Home Medical. A little bit of postage went a long way to save me so much money I don't even bother with the paper work to send it to Health Insurance.

  • Best price we could find!

    This review is for a 10-pack, not an individual filter, hence the best price around! Of course the quality is as good as any other brand filter, if not better. The shipping was super fast, arrived 2 days after order placed.

  • Quality inexpensive replacements.

    The replacement filters looked almost identical to the more expensive brand name ones. They seem to work as well as the original name brand. I was able to buy 10 of these filters for the same price as 2 of the name brand ones.

  • Ultra Fine Filters for PR System One, M-Series

    These are excellent filters. The only problem I have with them in that they are packaged in individual zip-lock plastic bags that contain no instructions to install the filters.

  • great price, great customer service

    I liked being able to buy these in bulk, and for not many, the price went WAY down. The customer service rep was friendly, helpful, and professional. She made the order great! I like being able to call in -- keeps me from ordering the wrong thing, which I have done in the past. Love this company and their products and PRICES.

    I like the fact that they removed the tab. However they also made the filters thinner and I do not believe that they do the same job.

  • Same filters, so much cheaper than my CPAP supplier

    I usually get my filters from the same company that I got my CPAP from, but their prices are outrageous. I got 18 filters for less than the price I normally pay for 6. I will only be ordering my filters from Direct Home Medical now.

  • Must Have for your CPAP

    I use a combination of the fine filter with the black foam filter. I just refuse to use my machine without either. It makes the difference between sleeping and not sleeping. I have always purchased all my cpap needs from Direct Home Medical and have never been let down.

  • CPAP Ultra fine filters

    I have found that using these OEM filters are easier to install and will stay in place better than the after market ones that my local medical equipment sells me. Buying 3 six packs at a time gives me a savings almost comparable to my out of pocket using my co-pay with my local merchant.
