Buyer’s Guide for the Best Smart Air Purifier

1. Filter replacement duration

Pleated filters should be changed every three to six months on average. Activated carbon filters should be changed every three months on average.

Most of the products come equipped with a sign light. This light shows you when it is time to replace (or clean) the filter.

2. Filter’s price

There is a wide range of prices for filters. If you are looking for large air purifiers, they fall in the range of twenty dollars to over two hundred dollars. You can spend up to $50 on filters that contain carbon to cut odors.

3. Certifications

There are a few labels on the packaging that you can pay attention to. The Energy Star logo is the first one. Purifiers with the Energy Star certification use 40% less energy than comparable models.

You can look for an AHAM Verified seal. This seal indicates that the air purifier has undergone testing. This testing is conducted by the Association of Home Appliance Manufacturers.

Many air purifiers have gone through AHAM’s voluntary certificate program. This includes room size recommendations. It also includes clean air delivery rates (CADRs) on the seal.

Higher CADR means the air purifier operates more quickly and efficiently. Room air purifiers with HEPA filters usually achieve the highest CADR.

CADR Value Rating
<240 Excellent
180-240 Very good
120-179 Good
60-119 Fair
>60 Poor

4. Room size

An air purifier with AHAM Verified seal can handle the indicated room size mentioned on the seal.

Also, models that are ideal for big rooms can also operate well for smaller rooms when the fan speed is lowered. Lower speed produces less noise. This is an advantage whether you’re trying to watch TV or taking a nap.

5. Noise

Air purifiers are required to run constantly. So, they should be silent. Check the product’s packaging or the product listing on the manufacturer’s website. This is to see if it includes the decibel(dB) levels of the various models.

For instance

Threshold of human hearing 0
Very quiet air purifier: 15dB
Whispering: 20dB
Good air purifier on low: 32dB
Typical air purifier on low: 36dB

How to Get the Most Out of Your Smart Air Purifier

Clean or replace filters time to time

If the filter is unclean, the device will not function effectively. If you have pleated filters, you should replace them every six to twelve months. If you have activated carbon filters, you should replace them every three months.

Place it wisely

If you have just one unit, put it in the room where you spend the most time. For most people, that’s the bedroom.

Some units are heavy and difficult to move around. So, if you want an air purifier in many rooms, you can buy a unit for each room. Place the air purifier in a spot where nothing can obstruct airflow. For instance, away from curtains.

Adjust the speed

We advise you to run the unit on its high-speed setting when you’re not in the room. Also turn it down to low when you’re close by to prevent noise interruptions. Alternatively, invest in an air purifier that suits a bigger space. This way you can operate it at a moderate speed and still get good results.

What types of filters should I look for?

Air purifiers are equipped with a wide variety of filters. These filters remove various types of contaminants from the air. When you have more of these, you will have a greater feeling of security as well as better hygiene.

Most products in the market are equipped with a HEPA filter. It removes minute particles from the air. There are also different grades of pre-filters that remove larger particles. These filters can be used in a variety of situations.

Some products utilize UV lamps, which are also capable of killing organic bacteria. Products with these characteristics have a higher price tag.

Ionizers can settle very fine particles in the air. This is another feature that is available on more advanced models.

Odors can be removed from the air using activated carbon filters. More filters are always better. But you should also pay close attention to the pricing while making a purchase.


A wide variety of smart air purifiers are available in the market. Some have an appealing design so that they look great in either your living room or bedroom.
