Ultimately, which air purifier is appropriate will depend on room size, available features, and individual air-quality level needs.
1. Is True HEPA necessary for allergies?
True, HEPA filters remove at least 99.97% of particles down to 0.3 microns, including pollen, pet dander, and dust mites, from the air.
2. What room size should I match with a purifier?
Look up the manufacturer's specifications for room coverage (in square feet/m²) and air changes per hour (ACH); oversizing guarantees quicker and more efficient purification.
3. How often do I replace HEPA filters?
Every 6-12 months, depending on usage and air quality, pre-filters may need to be cleaned more often.
4. Does auto-mode or air-quality sensor matter?
Indeed, this feature enables the purifier to control fan speed in response to real-time pollution levels, saving energy and extending the filter's lifespan.
5. Can this fully replace other allergy measures?
No, their help is considerable, but it's still not the best solution unless combined with other measures such as controlling indoor allergens, vacuuming, pet-free areas, and ensuring good air circulation in the rooms.
