Room by room

Find the right air purifier for every space

Tell us about your spaces and we'll match each one to the right purifier, showing the airflow (CADR), air changes per hour and noise level behind every recommendation. You can compare any model in any room, so nothing is a black box.

What counts as a room or space?

Think of a purifier like a heater. One heater in the hallway won't warm the whole house, so you put the warmth where people actually are. A purifier works the same way: it cleans the space it is in, but it won't effectively pull air through closed doors or around corners.

So add each space where people spend real time, usually bedrooms and the main living area, rather than the whole floor area of the house. An open-plan lounge, dining and kitchen counts as one space. A closed door helps a purifier work faster and more evenly, and you can skip the rooms nobody really uses.

Your setup

These apply to every room you add. You can leave them on the defaults.

3 air changes per hour

Air changes per hour (ACH) is how many times the purifier cleans the room's full volume each hour. We aim for at least 3 for comfortable everyday use. Go higher for busy or allergy-prone spaces, and 6 or more where many people share the air, like preschools, classrooms or waiting rooms.

What's driving this? Pick any that apply
Odours and VOCs are gases, so they need activated carbon, not just HEPA. We'll flag carbon status on every recommendation, and cover renovations and new home smell in your summary below.

Your rooms

Add each space you want covered. Every room gets its own recommendation, and you can flick between models to see how the numbers change.

Your plan

Everything in one place. Print it or email it to yourself, and get in touch if you'd like a hand deciding.

The honest bit. A purifier cleans particles from the air in the room it sits in. It won't lower CO2 (only fresh air does that), fix the source of mould or damp, remove all settled dust from surfaces, or cure a medical condition. Pair it with ventilation and normal cleaning for the best result. Coverage figures here assume the door is mostly closed and the unit has breathing room.
