Complete Air Purifier Buying Guide
Don't just buy any machine. Understand the technical specs to ensure you are effectively removing PM2.5, allergens, and odors from your specific room size.
Quick Tip
Always keep doors and windows closed while running your purifier for maximum efficiency. Replace HEPA filters every 6-12 months.
What is HEPA?
HEPA stands for High Efficiency Particulate Air. A True HEPA filter captures 99.97% of particles as small as 0.3 microns, including dust, pollen, mold, and bacteria. Always look for H13 or H14 grade HEPA for best results.
Filter comparison
How the HEPA grades stack up
Higher grade HEPA filters capture more microscopic particles and perform better over time.
HEPA Filter Efficiency Rating
Medical Grade HEPA (99.99%) > True HEPA (99.97%) > HEPA (99.95%) > Basic filters
Higher efficiency means better particle capture, especially for allergens and viruses.
Quick tip: If you have asthma or severe allergies, stepping up to H13 or H14 gives noticeably cleaner air.
Why is CADR important?
CADR (Clean Air Delivery Rate) measures how fast an air purifier can clean the air in a room. A higher CADR means faster cleaning. Typically, you want a CADR number that is at least 2/3 of your room's area in square feet.
Calculating Room Size
Measure the length and width of your room in feet. Multiply them to get the square footage. Choose a purifier rated for a slightly larger area than your room to ensure efficiency and lower noise operation.
Choosing for Specific Needs
For Asthma: Prioritize True HEPA. For Pets: Look for a strong Activated Carbon filter for odors. For Pollution/Smoke: High CADR and Activated Carbon are essential.
Understanding AQI
PM 2.5 vs PM 10
PM10 are larger particles like dust and pollen. PM2.5 are tiny particles (smoke, smog) that can enter your bloodstream. PM2.5 is the most dangerous.
Reducing Pollution
Use exhaust fans in the kitchen. Avoid incense sticks indoors. Keep shoe racks outside. Use air purifying plants like Snake Plant.
