How to choose
Consider Filter Efficiency
Look for HEPA filters rated at least 99% effective against particles down to 0.3 microns. This ensures removal of dust, pollen, smoke and other allergens.
Balance Price with Features
More expensive models often include additional features like activated carbon or UV-C light but may not offer significantly better purification performance for your needs.
Avoid Overlooking Size
Ensure the purifier covers room sizes matching where you plan to use it. Oversized rooms reduce effectiveness and increase energy costs.
