12 Best Cpap Filters of 2026 Reviewed

The 60-count RespLabs box is the lowest-cost way to keep a ResMed AirSense 10, AirCurve 10, or S9 on a two-week filter schedule for a full year. The non-woven media slides into the side slot without tools or adapters. The top pick’s 20-pack balances supply and fit, but this bulk set shifts the priority to per-filter price: roughly the same money for triple the filters. The 60 count means you don’t need to stock multiple boxes or remember a refill date.

This suits price-focused ResMed 10/S9 owners who accept the thickness trade-off of aftermarket media. It is not for AirSense 11 or DreamStation machines, and in a dusty room the media may need swapping before the two-week mark. Buyers who double filters to compensate will cut into the cost advantage. Affordable per-filter pricing makes an early swap painless.

Bay State’s 20-pack is built for the AirSense 11 rear slot, and the polypropylene media slides in flush without trimming or force. The 20 filters use an ultra-fine construction aimed at keeping dust and pet hair out of the machine’s intake while maintaining normal airflow. The filter body keeps its shape during handling, so the swap is a clean pull-and-replace job. That direct fit matters with this machine because the rear slot leaves less room for misaligned edges than older side-door designs.

The 20-count supply gives you a full replacement routine with room to spare, whether you stay on a monthly swap or follow a two-week cadence. For AirSense 11/AirCurve 11 owners who change filters regularly, the box is practical without pushing you into bulk inventory. The media seats squarely against the intake housing, so the seal stays consistent across all 20 filters. The filter media is dense enough to catch common household particles while still letting the AirSense 11 maintain normal pressure. The rear-slot mounting means there is no side door to open and no frame to assemble before each change. These are disposable filters, so the routine is simply pull, slide, and resume therapy.

AirSense 11/AirCurve 11 owners who want a 20-pack with a precise rear-slot fit are the right audience. This is a generation-specific filter, so older side-door ResMed machines require a different pack. The mid-range price makes sense for users who replace filters regularly and don’t want to store a year’s worth of filters at once. The 20-pack sits between trial packs and bulk boxes, which keeps storage low without leaving you short.

The Mars Wellness 24-piece combo gives DreamStation 1 owners four reusable pollen frames and 20 ultrafine disposables, covering a year of scheduled changes without committing to a 52-piece bulk box. It competes with larger budget kits on fit rather than sheer count: the media seats flush in the filter door, and the two-stage design works as well as OEM filters in daily use. That makes it the middle-ground option for buyers who want a practical rotation, not a warehouse supply.

This set is for DreamStation 1 owners who want a moderate year supply and don’t mind monthly disposable changes with quarterly foam washing. The replacement rhythm is clear: swap the ultrafine inserts every 30 days and clean the reusable foam every 90 days. It only fits DreamStation 1, so ResMed and DreamStation 2 owners should look elsewhere. Frame sturdiness is the minor durability trade-off: the reusable frames feel lighter than the original Philips parts, which matters if you handle them roughly.

The Medihealer 52-pack is the DS2 year-plus value kit: 22 pollen filters, 22 ultra-fine media pads, and four preassembled filters. The 52-piece count lines up with the every-two-week replacement rule, covering a year-plus of DS2 maintenance without a reorder, and the per-filter cost stays within budget range for a machine-specific refill.

The remaining 48 media pads mount into reusable frames. Some media pieces need careful seating in the frames, so this kit favors DS2 owners who are comfortable with assembly-based filter changes. ResMed and DreamStation 1 machines are outside its compatibility.

The two media types split the DS2’s intake duty: the pollen foam catches the coarse household dust, and the ultra-fine pad handles finer particles. The frame design keeps swaps quick once media is seated, so routine changes don’t turn into a project.

IBEET’s 52-piece set gives DreamStation 1 owners a year-plus supply at a per-filter price below DME pricing. Reusable frames cut waste: swap the foam or ultra-fine media instead of discarding a whole filter. Fit is secure, and it works as an OEM-style replacement. The tradeoff is media consistency: airflow and filtration density can vary between packs, so this bulk option trails the balanced combo in this lineup. It suits buyers who inspect filters at each change and don’t demand OEM-identical density. AirSense or DreamStation 2 owners need a different filter.

The Medihealer kit packs 52 pieces for the DreamStation 1 and lands at a per-filter price that undercuts typical DME refills. Inside are four assembled frames plus 22 foam and 22 ultra-fine inserts, so each layer has to be seated into the reusable frames before use. Fit is generally good for the DS1, but the listing lacks detailed specifications and filtration effectiveness can vary — a boundary worth respecting if you need maximum filtration certainty. For budget-focused owners who don’t mind assembly, this is a strong supply play.

The Timok 40-pack gives ResMed AirSense 10, AirCurve 10, S9, and AirStart owners a 5-layer ultra-fine filter at a rock-bottom per-filter price. The dimensions align with the stock filter slot and the media holds up between changes. Pack-to-pack fit can vary, which keeps it behind the Bay State 20-pack. Not for AirSense 11 or DreamStation; it’s a cost-saving trial option before committing to a larger bulk pack.

RespLabs packs 60 rear-slot filters for the AirSense 11/AirCurve 11 at a price that keeps the two-week change schedule affordable for a full year. The media runs thinner than OEM, which can push buyers toward doubling filters — a workaround that eats into the cost advantage. Fit is generally precise, but the occasional size variance between packs makes a quick rear-slot seal check after install worthwhile. The top AS11 pick uses denser media with more consistent fit, which is where this bulk pack trails.

This 27-piece USA-made kit pairs 9 reusable frames with 18 ultrafine disposable filters, so DreamStation 1 owners can rotate supplies without ordering two separate products. The reusable frames rinse clean for extended use, while the ultrafine media handles routine household dust between swaps. The per-filter price runs higher than the leading bulk DS1 combos, which is why it sits below the bigger value kits in this roundup.

The ItAll kit gives DreamStation 2 owners a 52-piece supply with six reusable frames, so the replacement schedule is covered for roughly 18 months. The foam and ultra-fine media seat cleanly into the frames, and the fit stays secure during routine swaps. It is a viable alternative to the larger DS2 kits, though availability is more limited than the other 52-piece DS2 kit. ResMed owners and anyone wanting fully pre-assembled disposables should look elsewhere.

Sixty filters in the box bring the per-filter cost down for AirSense 11 owners, and the slide-in rear-slot design needs no modification. Media density is adequate for standard bedroom filtration, and a two-week change cadence stretches one box to a full year. Occasional size variance can require a firm press to seat, so this is a budget value play rather than the fit-and-finish leader in the AS11 category.
