Air Purifier Buying Guide

Not sure which air purifier is right for you? Here's what to consider:

📏

Room Size

Match the purifier's coverage area (measured in m²) to your room size. For best results, choose a unit rated for a slightly larger area than you need.

🌀

Filter Type

True HEPA filters capture 99.97% of particles as small as 0.3 microns. Look for H13 or H14 rated filters for the best air purification.

🔊

Noise Level

For bedrooms, look for units under 40dB on low settings. Check the noise level on both low and high fan speeds.

📈

CADR Rating

Clean Air Delivery Rate measures how quickly a purifier filters air. Higher CADR means faster purification - aim for at least 150 m³/h.

💰

Running Costs

Consider energy consumption and filter replacement costs. Some filters last 6-12 months, others up to 2 years. Factor this into your budget.

📱

Smart Features

App control, air quality displays, and auto modes add convenience. Decide which features matter most to your lifestyle.
