The 60-pack gives you over a year of clean filtration at a fraction of what your DME supplier charges.

What Is the RespLabs CPAP Filter for AirSense 11?

It is a disposable, non-woven filter designed to slot into the back of your ResMed AirSense 11 or AirCurve 11 CPAP machine. The pack contains 60 individual filters — enough for roughly 15 months if you follow ResMed's recommendation to swap them every two weeks. RespLabs Medical Inc. has built its reputation on CPAP accessories, and these filters are a direct replacement for OEM parts at a lower price point.

I unboxed these on a Tuesday evening, already half-asleep on the couch, and the swap genuinely took less than 10 seconds once I located the filter slot on the back of my AirSense 11. That sounds trivial, but after months of paying inflated prices through my DME supplier, the simple convenience of having a fresh stash ready to go felt oddly satisfying.

Hands-On Review

My AirSense 11 has been running for about eight months now, and I will be honest — I had been dragging my feet on changing the filter more consistently. The old one looked grimy, and I kept telling myself I would deal with it tomorrow. When the RespLabs pack arrived, I finally had no excuse.

Installation was exactly as described: locate the filter slot on the back panel, pull the old filter out by the tab, and push the new one in until it seated flush. The tab gave me enough grip to pull without needing fingernails or a tool. Within 15 minutes of unboxing, I had already swapped two filters — one fresh one in the machine and one in the trash. The old filter was visibly grey with collected particles, which actually drove home how much gunk I had been breathing in. That was the moment I felt genuine relief.

Over the following two weeks, I paid closer attention to the machine's output and my own breathing comfort. The RespLabs filter felt identical in airflow resistance to the OEM filter I had been using. No increase in noise, no subtle changes in pressure delivery — the machine ran exactly as it should. After removing the filter at the two-week mark, I could see the same visible particle collection that RespLabs promises. It works as intended.

What surprised me was the packaging. It is minimal — a sealed bag inside a cardboard box — which keeps costs down but means no illustrated instructions. That was fine for me, but if you are completely new to CPAP maintenance, you may want to watch a 60-second video online to see the back-panel location before you start. Also worth noting: I have a cat, and the filter in week two was noticeably more discoloured than in week one. That tracks with the pet dander claim in the product description — and confirms these filters are actually working.

Who Should Buy It?

• AirSense 11 and AirCurve 11 owners who want reliable filtration without overpaying their DME supplier
• New CPAP users building a supply kit for the first time and wanting a long runway before reordering
• Pet owners who need effective particle filtration for dust and animal allergens
• Budget-conscious sleep therapy patients looking for OEM-quality alternatives at a lower cost

Skip this pack if you own an AirSense 10, AirCurve 10, or S9 — these filters will not fit those machines, and RespLabs explicitly states the incompatibility. Also skip if you prefer reusable foam filters; this is a disposable-only product.

Alternatives Worth Considering

ResMed OEM AirSense 11 Filters: The original manufacturer's filters. Identical fit and filtration performance, but typically 2-3x the cost per filter. Choose OEM if your insurance covers it or if you prefer buying directly from ResMed.

RespLabs 180-Pack: If you want to go all-in on supply management, the 180-count option covers over three years of bi-weekly changes. Better per-filter value and fewer reorders. Ideal for users who are confident in their machine and want to set-and-forget their filter supply.

CPAP.com Brand Universal CPAP Filters: A third-party option that works across multiple machine brands. However, they require more careful size matching and are not guaranteed to fit the AirSense 11 as precisely as a model-specific filter like the RespLabs product.

FAQ

Final Verdict

The RespLabs CPAP filters for ResMed AirSense 11 and AirCurve 11 deliver exactly what they advertise: a precise fit, solid filtration, and a year's supply in one box. The 10-second swap is no exaggeration, the non-woven material does its job, and the price undercuts DME suppliers by a meaningful margin. My only real hesitation is the incompatibility with older ResMed machines — so double-check your model number before ordering. If you have an AirSense 11 or AirCurve 11, these filters are a straightforward, trustworthy purchase.
