Air Purifier Buying Guide
1. Match Coverage to Your Room Size
The most important spec is the CADR (Clean Air Delivery Rate) and the recommended room coverage. A purifier rated for 200 sq ft will struggle in a 400 sq ft living room. Always size up slightly to ensure efficient filtration.
2. Look for True HEPA (or H13 HEPA) Filters
True HEPA filters capture 99.97% of particles at 0.3 microns. H13 medical-grade HEPA goes even further, capturing 99.9% of particles at 0.1 microns. Avoid “HEPA-type” or “HEPA-style” filters — they don’t meet the same standard.
3. Consider Ongoing Filter Costs
Replacement filters typically cost $20–$50 and should be replaced every 6–12 months. Factor this into your total cost of ownership. Some models have washable pre-filters that extend the life of the main filter.
4. Noise Level Matters for Bedrooms
If you plan to run an air purifier while sleeping, check the decibel rating on the lowest setting. Models under 30 dB are essentially silent. Look for a dedicated sleep mode that dims indicator lights and locks the fan to a quiet speed.
Frequently Asked Questions
Do air purifiers actually work?
Yes — air purifiers with True HEPA filters are scientifically proven to remove airborne particles including dust, pollen, mold spores, pet dander, and some bacteria and viruses. Studies consistently show they reduce indoor particulate matter, which can benefit people with allergies and asthma.
How often should I run my air purifier?
For best results, run your air purifier continuously, especially in rooms where you spend the most time. Most models have an auto mode that adjusts fan speed based on air quality, keeping energy use low when the air is already clean.
Where should I place my air purifier?
Place it in the room you use most — typically the bedroom or living room. Position it where air can circulate freely (not tucked in a corner or blocked by furniture). Avoid placing it near walls or curtains that could block airflow.

You don’t need to spend hundreds of dollars to get genuinely clean air. Our top pick overall is the Coway AP-1512HH — it covers a large room, uses a smart auto mode, and has proven long-term reliability. For pet owners, the Levoit Core P350 is purpose-built for your needs.
