How to Choose the Best Air Purifier for Your Home

How do you choose the best air purifier? What functions and features should the ideal air purifier have? Read our guide and make an informed choice.

Indoor air pollutants are a source of concern especially for those of us who are more sensitive or allergic.

Certain studies conducted by environmental agents have revealed that in some situations the air quality inside a home is up to several times worse than outdoor air.

Why Choose the Best Air Purifier?

The best air purifier can help you fight air pollutants with advanced filters that can keep dust, pollen and other known allergens out of your house.

An air purifier mounted in the bedroom or in the living room can filter the polluted air from the areas where you spend the most time with your loved ones. These devices are available in a wide range of models and offer varying levels of air filtration.

How to Choose the Best Air Purifier

The best home air purifiers efficiently remove harmful particles and work silently. The main criteria for evaluating the best air purifier are filtration efficiency, coverage area, noise level, safety of use, energy consumption, additional functions and manufacturer’s warranty.

Below we will detail the important aspects to help you choose the right air purifier for you.


Futuristic design and advanced features are welcome, but the most important aspect to consider in an air purifier is its ability to clean the air.

Choose an air purifier with a high flow rate that efficiently filters the cigarette smoke, dust and pollen from the air. Some devices will display the volume in cubic meters (m³) or in square meters (m²). In square meters, we assume that it refers to the size of the room calculated at a standard ceiling height of not more than 2.5 meters.

Generally, it’s good to choose an air purifier that has a bit bigger processing capacity than the room where you want to use it to get maximum efficiency.

Operating Noise

Finally, you’ll have to compromise between a silent purifier and a more noisy but more powerful one. A silent appliance will not process a large amount of air, so you will need to choose the quietest air purifier for the amount of air you need to filter.

To evaluate this, you will need to look at the decibel level of similar filtering devices and choose the quietest. The higher the decibel level, the more noisy the air purifier will be during operation.

Safety and Certifications

Several independent certifications of the chosen purifier may indicate safety in operation.

Some models are certified by ECARF (European Center for Allergy Research) or by other independent laboratories. In addition, check whether the chosen model is also certified for energy consumption by an authorized body.

Certain models of air purifiers can generate other harmful particles in the process of filtering common pollutants.

The most common problem is the excessive generation of ozone particles that are not very beneficial in quantities above the permitted limits.

For those suffering from asthma and allergies, long exposure to ozone particles may damage health and may aggravate respiratory problems, causing chest pain, difficulty in breathing and respiratory irritation. The best air purifiers destroy ozone particles in the air, thus preventing unpleasantness.


Comfort in use is an important factor in choosing the best air purifier. Many devices use replaceable filters that are monitored to indicate when to change. In addition, look for a cleaner that has timer programming functions for stopping or starting.

This way you can program your device to operate for a limited time to prevent premature filter wear and to function optimally when you are away from home or during sleep. Many air purifiers are equipped with a remote control to ease their use, although not always necessary.

The best air purifiers use an air quality sensor that allows them to adjust the fan speed according to the particle density in the atmosphere.

This function is excellent because you will not have to adjust the speed manually. In addition, it allows you to program the device and automatically operate it.

Service and Warranty

Operating an air purifier should not be difficult, but it is good to get support from the manufacturer if something does not work properly. Choose a device made by a reputable company that offers you a maximum guarantee and service at your fingertips.

The best air purifier will keep your home clean and free from dust, odours and allergens, thus minimizing pollutants in the breathing air. This way you can be sure that the whole family will enjoy a safer atmosphere away from unwanted allergies and irritations.
