1. Levoit Core 300S-P Smart Air Purifier — $100

Best budget. Small rooms (200 sq ft). Quiet enough for a bedroom. Filters $25 each, every 6–12 months. The most popular HSA-purchased air purifier on Amazon.

2. Coway Airmega 200M — $229.99

Best mid-range. Medium rooms (361 sq ft). 4-stage filtration including HEPA + activated carbon. Wirecutter's longtime top pick.

3. Honeywell Allergen Plus HPA5300B — $319.95

Best for asthma. Large rooms (465 sq ft). Allergy-grade HEPA, AHAM-certified. Better filtration than mid-range options. Replacement filters every 12 months.

5. Dyson Purifier Cool PC1 — $449.99

Premium. Doubles as a fan, adding cooling to filtration. Strong LMN case for severe allergies + summer cooling needs.

6. Coway Airmega 400 — $649.00

Best for very large rooms (1,560 sq ft). Use for whole-floor or open-concept living spaces. One unit instead of multiple smaller ones.

The bundle play

One LMN can cover purifier + replacement filters (recurring) + hypoallergenic bedding + dust-mite covers. Get the LMN once from your allergist or PCP, then reorder filters indefinitely under the same letter as long as your condition persists. Caeli auto-tracks LMN expiration so you never reorder under expired paperwork.

Caeli Pro-Tip

Caeli flags eligibility on Amazon, Coway, Dyson, brand-direct purifier sites. Integrated telehealth issues the LMN; the auto-archive saves it; renewal alerts keep your filter purchases pre-tax indefinitely. Install Caeli and let your allergies pay you back.

Frequently asked questions

Is Levoit Core 300 HSA-eligible in 2026?

Yes — with an LMN tied to allergies, asthma, or another respiratory condition. The Core 300 ($100) is one of the most commonly LMN-purchased purifiers.

Are replacement filters HSA-eligible?

Yes — under the same LMN as the purifier itself. Filters typically need replacement every 6–12 months, and they remain LMN-covered as long as your condition persists.

Does my HSA cover a Coway Airmega 400 for a large room?

Yes with an LMN. The Coway Airmega 400 ($400) is rated for very large rooms; LMN-eligible for documented respiratory or allergy conditions.

Can I use my FSA for a Dyson air purifier?

Yes with an LMN. Same rules as HSA. Dyson's higher price point is fully reimbursable if your LMN is well-documented.

Can my LMN cover multiple air purifiers (one per room)?

Yes — if your home has multiple rooms where you need clean air (bedroom, living room, child's room), the LMN can specify multiple units. Most allergists will write this if asked.

Bottom line

Pick the right size for your room. Get one LMN that bundles purifier + filters + bedding. Your HSA pays for all of it pre-tax, indefinitely. Caeli automates the eligibility check and keeps the LMN active.

Install Caeli and breathe pre-tax.
