Buying Guide
What to consider when choosing CPAP inline HEPA filters
- Compatibility: Confirm inlet/outlet sizes (22mm tubing, 25mm machine outlet) and whether the filter supports your CPAP or BiPAP model.
- Airflow impact: Look for low flow resistance to minimize any effect on therapy pressure and flow at 30 LPM or higher.
- Pack size: Choose a pack size that matches your replacement schedule; larger packs may reduce overall cost per filter.
- Installation: Ensure the filter installation steps match your tubing configuration so there are no leaks or dead spaces.
- Filtration efficacy: High-density or enhanced filtration helps capture dust, debris, and odors for cleaner air.
- Durability and materials: Seek filters designed to endure regular use without losing structural integrity.
- Manufacturer guidance: Follow product notes about compatibility and installation to avoid mismatches with your setup.
How to compare filters quickly
- Compare pack size and price per filter to estimate annual cost.
- Check reported flow resistance figures (mmH2O) at a standard 30 LPM to gauge impact on therapy.
- Prioritize models with clear compatibility notes for 22mm tubing and 25mm outlets.
- Consider whether a brand offers easy return policies or customer support for fit questions.
Maintenance and replacement tips
- Replace filters on a regular schedule based on usage, environment, and moisture exposure.
- Store spare filters in a clean, dry place to avoid contamination before use.
