Air Purifier Comparison Questions
What's the most important factor to compare?
CADR rating is the most critical factor - it determines actual cleaning performance. Make sure the CADR matches or exceeds your room size requirements.
Should I prioritize price or performance?
Consider total cost of ownership over 5 years, including filters and energy. A more expensive unit with lower operating costs often provides better value.
How important are smart features?
Smart features like air quality sensors and app control add convenience but shouldn't be the primary deciding factor. Focus on core performance first.
What noise level is acceptable?
For bedrooms, aim for under 30 dB on lowest settings. Living areas can handle 35-40 dB. Check noise at different fan speeds, not just maximum.
How do I compare filter costs fairly?
Calculate annual filter cost: (filter price × 12) ÷ filter lifespan in months. Some cheaper units have expensive filters that add up over time.
Should I buy the highest CADR available?
Not necessarily. Higher CADR units cost more and use more energy. Choose CADR that's 20-30% above your calculated needs for optimal efficiency.
Why Compare Before You Buy?
Save Money
Avoid overpaying for features you don't need or buying undersized units that require expensive upgrades later.
Get Better Results
Choose the right specifications for your specific room size, health needs, and usage patterns for optimal air quality.
