FAQ
What size air purifier do I need for my room?
Measure your room's square footage and choose a purifier rated for that size or larger. For best results, select a model rated for 1.5x your room size - this allows the purifier to clean air faster and run on quieter, lower settings.
How often should I replace air purifier filters?
Most HEPA filters need replacement every 6-12 months, depending on usage and air quality. Pre-filters should be cleaned monthly. Some models have filter replacement indicators. Budget $30-70 per year for replacement filters.
Are air purifiers worth it for allergies?
Yes, HEPA air purifiers can significantly reduce airborne allergens including pollen, dust mites, and pet dander. Studies show they can reduce allergy symptoms, especially when combined with regular cleaning and low humidity.
Do air purifiers help with wildfire smoke?
Yes, True HEPA purifiers can capture fine particulate matter (PM2.5) from wildfire smoke. For smoke, look for high CADR ratings and consider adding an activated carbon filter to help with odors.
Are ionizers and PlasmaWave safe?
Modern ionizers like Winix's PlasmaWave are designed to be ozone-safe and can help neutralize airborne pathogens. However, if you have respiratory sensitivities, you may want to stick with mechanical HEPA filtration only.
