The 2026 Ultimate Guide to FSA & HSA for CPAP: Rules, Eligibility, and Smart Buys

The end of 2026 is coming fast. If you have money sitting in a Flexible Spending Account (FSA), most plans give you until December 31 to spend it before it's gone for good.

The "use it or lose it" rule catches thousands of people off guard every year, leaving real money on the table.

The good news?

Your CPAP therapy is one of the smartest ways to spend those pre-tax dollars. Whether you need a backup battery for storm season, a fresh mask that actually seals, or a travel machine for your next trip, your FSA or HSA can cover it.

This guide covers the 2026 rules, what's changing for 2027, and exactly what to buy so none of your balance goes to waste.

FSA vs. HSA: What's the Difference?

Both accounts let you pay for CPAP gear with pre-tax dollars, but they work very differently. Knowing which one you have tells you how fast you need to act.

2026 and 2027 FSA/HSA Limits

The IRS adjusts these limits for inflation every year. Here are the numbers that matter for spending down your 2026 balance and planning your 2027 contributions.

Sources: IRS Rev. Proc. 2025-32 (2026 FSA), Rev. Proc. 2025-19 (2026 HSA), and Rev. Proc. 2026-24 (2027 HSA). The IRS typically announces the next year's FSA limit in the fall; we'll update this table when it does.

What the carryover rule really means

The carryover is the most important number for FSA holders. If your plan allows it, up to $680 of unused 2026 money can roll into 2027. Anything above that is forfeited.

Some employers offer a grace period instead, which gives you up to two and a half extra months (usually until March 15) to spend your balance. Plans can offer a carryover or a grace period, but not both, and some offer neither. Check with your plan administrator so you know which rule applies to you.

Is a CPAP Machine FSA Eligible?

The short answer is yes.

CPAP machines are FDA-regulated medical devices used to treat sleep apnea, which makes them qualified medical expenses for both FSA and HSA spending.

That applies to every machine we carry. Whether you're upgrading to a home machine like the ResMed AirSense 11 or picking up a travel unit, you can use your pre-tax funds to cover the full cost.

Travel CPAP Machines: A Smart Use of Funds

If you have a large FSA balance (over $800) that you need to spend quickly, a travel CPAP machine is one of the best purchases you can make.

To the IRS, a travel machine is a medical device, just like your home unit. That means your pre-tax dollars cover it in full.

Instead of losing your balance on December 31, you get a backup machine that makes every trip, camping weekend, and hurricane evacuation easier.

Which CPAP Supplies Are FSA Eligible?

You don't need to buy a machine to use up your funds. Most of our customers spend their balance stocking up on supplies they know they'll need next year anyway.

Nearly every part of your therapy qualifies. Here's what you can buy without any special paperwork:

• CPAP Masks: Every style qualifies, including nasal pillows, nasal masks, and full face masks like the ResMed AirTouch F40. Every mask comes with our 30-day mask exchange guarantee, so if it doesn't work for you, we'll swap it for one that does.
• CPAP Battery Backup: This is huge for our Florida customers. Backup batteries like the Freedom CPAP Battery 160 keep your therapy going during power outages and hurricanes, not just on camping trips.
• Cleaning Supplies: CPAP wipes, tube brushes, and mild soaps.
• Replacement Parts: Filters, water chambers, heated tubing, and chinstraps.
• Comfort Accessories: CPAP pillows (with cutouts for your mask) and mask liners.

Your Year-End Supply Checklist

Before December 31, walk through your whole setup and replace anything that's worn, stretched, or cloudy. Going category by category makes it easy to get everything you need in one order.

Are CPAP Sanitizers FSA Eligible?

Automated cleaners like the SoClean 3 and the Liviliti Paptizer 360 are popular upgrades for keeping your equipment clean without the daily soap-and-water routine.

Are they FSA eligible? Often, yes, but it depends on your plan administrator.

Many plans approve them, while stricter ones treat sanitizers as general wellness products rather than medical necessities. If your plan asks for more information, a Letter of Medical Necessity (LMN) from your doctor stating the device helps prevent infection usually settles it. Check your plan's rules before you buy.

Frequently Asked Questions

What is the FSA limit for 2026?

What happens to my FSA money if I don't spend it by December 31?

Usually you lose it. That's the "use it or lose it" rule. Some plans let you carry over up to $680 into 2027, and others give you a grace period of up to two and a half months instead. Check your plan's rules so you know your real deadline.

Are travel CPAP machines FSA/HSA eligible?

Yes. Travel CPAP machines like the AirMini and Transcend Micro are medical devices, so they're qualified expenses just like a home machine.

Are CPAP batteries and backup power supplies eligible?

Yes. Backup batteries are eligible because they keep your therapy going during power outages, storms, and travel.

Are CPAP sanitizers like SoClean or Liviliti FSA eligible?

It depends on your plan. Some administrators approve them automatically, while others ask for a Letter of Medical Necessity (LMN) from your doctor. Check with your plan administrator before you buy.

Are CPAP wipes and soaps FSA eligible?

Yes. Supplies used to keep your CPAP equipment clean, such as wipes, tube brushes, and mild soaps, are generally eligible.

Are CPAP pillows and mask liners eligible?

Yes. Accessories designed for CPAP therapy, like contour pillows that reduce mask leaks or cloth liners that prevent skin irritation, are eligible.

Can I use my FSA to buy CPAP supplies for my spouse?

Yes. The IRS lets you use FSA funds for qualified medical expenses for your spouse and tax dependents.

Do I need a prescription to buy a CPAP machine with my FSA or HSA?

Yes. We need a valid prescription on file before we can ship a CPAP machine, no matter how you pay. You can check out first, then pick how to send it. Our Rx Renewal Service is free with any CPAP machine purchase and gets you a new prescription within one business day.

Do I need a prescription to buy a mask?

No. You can order a complete mask without a prescription. If we don't have one on file, we'll ship your mask in parts automatically.
