Air purifiers for everyday spaces

An air purifier draws air through a filter to help capture airborne particles. Depending on the model and its filter, that can include dust, pollen and other particles moving through a room. If you're choosing a room air purifier for a bedroom, study or living area, start with the space it'll be used in and the filter it'll need over time.

What can an air purifier do at home?

Dust and pollen don't always stay on surfaces. Some particles can remain airborne as people move around the house or open a door. An air purifier can help reduce the particles its filter is designed to capture as air passes through the unit. It's a useful addition to everyday cleaning, especially in a room where you spend a lot of time.

Filters and performance vary between products, so check the individual listing for what a model is designed to filter. An air purifier won't remove every particle or replace dusting, vacuuming and ventilation. For dust that's already settled on floors and furnishings, browse our vacuum cleaners as part of your regular cleaning routine.

Match a room air purifier to your space

Check the room coverage listed for each model against the area where you plan to use it. A closed bedroom and an open-plan living space may call for different options. If the listing provides a recommended room size, use that figure to narrow your choice rather than judging by the purifier's physical size.

Think about where the unit will sit, too. Look for a spot near a suitable power point where furniture and curtains won't block its air inlets or outlets. Follow the product's placement and clearance instructions, and check its dimensions if bench or floor space is limited.

Compare filters, settings and upkeep

The filter is an important part of choosing an air purifier. Check which type comes with the unit and what the product information says it captures. If a particular feature matters to you, such as a HEPA filter, confirm that it's listed for the specific model you're considering.

Look at the available settings in the product details. Fan speeds, timers and display controls can make a difference to how you'll use the purifier through the day or in a bedroom at night. If you plan to move it between rooms, check its weight and whether its listed coverage suits each space.

Filters also need ongoing care. Check whether a compatible replacement filter is available and note the model number so you can find the right one later. Follow the instructions for cleaning or replacing it; the timing and method can differ between products.
