How We Evaluated

Here’s what I focused on while testing these units:

• Performance: Clean Air Delivery Rate (CADR) ratings and real-world effectiveness against dust, smoke, and allergens.
• Noise Level: Because nobody wants a jet engine in their bedroom.
• Filter Cost and Replacement Frequency: The hidden ongoing costs that manufacturers don’t advertise.
• Room Size Coverage: Making sure the unit actually works for your space.
• Value for Money: Price relative to what you actually get.

Buying Guide

Here’s what actually matters:

• Room Size: Get one rated for your actual room size, not smaller. CADR ratings tell the real story.
• Filter Type: HEPA for allergens, activated carbon for odors. Most decent units have both.
• Noise Levels: Check reviews for bedroom use – specs lie, but users don’t.
• Maintenance Costs: Factor in filter replacements. Some “cheap” units cost more long-term.
• Portability: If you want to move it around, weight and size matter more than fancy features.
