What Should You Look for When Buying an Air Purifier?

There are certain things that you should remember before buying an air purifier. Let’s have a look-

1. CADR

CADR is an important factor for an air purifier. CADR (clean air delivery rate) is a rate that indicates the volume of purified air (in cubic meters) produced by the air purifier every hour. If the CADR is high then the purifier can filter the air more quickly.

For installing the air purifier in a bedroom having an area up to 350 square feet, go with an air purifier that provides a coverage area of at least 370 to 400 square feet with the CADR value between 150 to 250-meter cube per hour.

For installing the air purifier in the living room having an area in the range of 350 to 700 square feet, purchase an air purifier that provides a coverage area in the range of 400 to 750 square feet with the CADR value of 250 to 350-meter cube per hour.

For installing the air purifier for purifying the entire house i.e. for areas beyond 700 square feet, go with an air purifier that provides a coverage area in the range of 800 to 1200 square feet with the CADR value of 400-meter cube per hour and beyond.

In addition to this, what one must ensure is the level of noise produced by the air purifier when in use is under permissible limits. As a rule of thumb, noise levels below 60 dB are considered safe for prolonged use.

2. Coverage area

coverage area is how much area an air purifier can cover. More coverage area means you can use it for a large room or hall. With less coverage area you can cover only a small-sized room.

3. Power consumption

Power consumption is a point you should definitely look after. Power consumption should be within a maximum of 60 watts. It is advisable to opt for a low power consumer purifier. It will save your electricity bill.

4. Child lock

If you have children in your house then you should definitely buy an air purifier with a child lock feature. Child lock secures the purifier from your toddler. It also prevents any accidental changes in the setting of the purifier.

5. Sleep mode

Sleep mode or night sense mode constantly monitor your room’s air quality and prepare your bedroom air for sleep. By enabling sleep mode the purifier produces a low sound which helps you to sleep better.

6. Auto purification mode

For activities like cooking, cleaning if the PM2.5 level increase above local guidelines, auto purification mode can detect the level of indoor pollution and boosts its speed to deal with the pollution. So, it’s worth looking for an auto purification feature in the purifier.

7. Filter change indicator

Every air purifier comes with different filters. Filters are essential for removing the dust, pollen, allergen, etc. Every filter has a filter life. After ending the filter life you have to change the filter in order to get benefits from the air purifier. The filter change indicator lets you know when it’s time to change the filter.

8. Air quality indicator

The air quality indicator helps in indicating the air quality in the room. Air purifiers with AQI feature indicate the air quality through colored LED lights. You can adjust the speed of the appliance by viewing the lights. However, some high-quality air purifiers come with an automatic mode feature, which detects the air quality and works accordingly. In those air purifiers, you don’t have to change the speed manually. Some air purifiers come with a numeric PM2.5 display which helps to measure the air quality. Brands like Philips, Xiaomi, Honeywell comes equipped with real-time PM2.5 display.

Hopefully, with this guide, you can get the best air purifier for your home with a budget under $100.
