Unoovo Portable HEPA Air Purifier 160 CADR up to 30 sqm Room

What's CADR?

CADR (Clean Air Delivery Rate) measures how much clean air a purifier moves. Powerful air purifiers for larger rooms have a higher CADR.

It's typically measured in cubic feet per minute (CFM) or cubic meters per hour (m³/h).

Choose a purifier with a higher CADR than you need. This allows you to run it at lower fan speeds for quieter operation and improved energy efficiency.

What's ACH?

If you've been researching air purifiers, you've probably come across the term ACH (Air Changes per Hour).

ACH measures how often an air purifier completely refreshes the air in a room within an hour. For example, a rating of 4 ACH means the air is fully filtered and replaced four times every hour. Ideally, you should aim for at least 4.8 ACH for effective purification. We've prefilled this option for you.
