Air Purifier Tips: Choose, Use, and Keep Your Home Fresh

Feeling the air in your house is stuffy or you notice dust on surfaces? An air purifier can help, but you need to know how to pick the right one and keep it running well. Below are simple steps you can follow right now.

Choosing the Right Air Purifier

First, check the room size. Look at the CADR (Clean Air Delivery Rate) number on the box – the higher it is, the bigger area it can clean. If the CADR is too low for your room, the unit will struggle and use more electricity.

Next, think about the pollutants you care about. For smoke or pet dander, a HEPA filter is a must. If you worry about odors or chemicals, add an activated carbon layer. Some models combine both, which is a good all‑round choice.

Price matters, too. You don’t need the most expensive model to get clean air. Look for a unit with a washable pre‑filter and a replaceable HEPA filter that costs less than £30 a year.

Keeping It Working Perfectly

Place the purifier where air can flow freely – open space, not tucked behind furniture. Keep it at least a foot away from walls and vents. This lets the fan pull in dirty air and push out clean air without blockage.

Replace or clean the filters on schedule. A good rule is to check the pre‑filter every month and the HEPA filter every 6‑12 months, depending on use. If you notice a drop in airflow or a weird smell, it’s probably time for a change.

Turn the unit on when you’re home and close doors to keep the clean air inside. If you’re away for a day, you can switch it off to save energy, but leave it on at night if allergies bother you.

Mold can show up in humid rooms. An air purifier with a UV light may help, but the real fix is to lower humidity with a dehumidifier or improve ventilation. Removing mold at the source is more effective than relying on the purifier alone.

Finally, monitor your results. If you still see dust or notice sneezing, try moving the purifier to a different spot or upgrade the filter type. Small adjustments often make a big difference.

By following these tips, you’ll get cleaner air without spending a fortune or dealing with constant filter swaps. Breathe easier and enjoy a fresher home today.
