How Many Air Purifiers Do I Need? The Simple 2025 Guide

How Many Air Purifiers Do I Need? (One Might Be Enough!)

Do you really need multiple air purifiers? Many think they need a clean air purifier in every room. But with smart planning, one powerful unit can clean your entire space. Here’s how to simplify your life and breathe easy.

The Power of CADR: One Unit, Full Coverage

CADR (Clean Air Delivery Rate) measures an air purifier’s cleaning speed. Higher CADR = larger coverage. Forget multiple units – match CADR to your room size:

Brands like Berk label CADR clearly. An 800 CADR model cleans 100 m² completely!

Why One High-CADR Purifier Wins

3 Steps to Find Your Perfect Fit

1. Measure Your Space

• Calculate square footage in square meters:

• Length × width (e.g., 10m × 10m = 100 m²)

• Note ceiling height: Over 2.7m? Add 20% CADR

2. Choose Your CADR Hero

• For 100 m² → 800 CADR

• For 150 m² → 1,200 CADR

3. Place It Strategically

• Room where you spend the most time (usually living room)

• Central location

• 1 meter from walls/furniture

When You Might Need Extra Units

✅ Multi-Level Homes: One unit per floor
✅ Closed-Off Rooms: Bedrooms with allergies
✅ Special Zones: Kitchens (grease) or basements (mold)

5 Signs One Purifier Isn’t Enough

1. Dust piles up in far corners

2. Pet dander triggers allergies in unused rooms

3. Smells linger in closed areas

4. Your space has separated zones (e.g., hallway barriers)

5. You have over 150 m² with low ceilings
