Things to be considered while buying the best air purifier…

An air purifier is a compact system that eliminates dirt, smoke, pet hair and dander, dangerous allergens, and several other volatile contaminants from the air. Therefore, if you have any of these situations, you must think about purchasing an air purifier.
Air purifiers are known medically for dropping allergy symptoms, dropping asthma, sufficient sleep, easy to breathe, and creating an overall excellent standard of living.

Here’s a buying guide to decide the best air purifier for your house.


The size of the room is an essential part to consider while selecting an air purifier. Large rooms need more air to cover the spaces and vice versa. The market is overflowed with plenty of air purifiers and possible in all sizes varying from compact to heavy. So, ensure to compare the coverage area parameter with the room size you wish to purify. It is prudent to opt for a system designed to clean the air in a slightly larger space than the original room size.

Filter type:

Although many companies require producing the best air purifiers with low-grade characteristics, when compared to its price and, the type of filter used in it shows a valid reality. Several kinds of filters aim for different air components like bacteria, viruses, allergens, and ultrafine particles, etc. It’s sufficient to go for a HEPA filter, which is famous for its unbelievable performance and efficiency of purifying all kinds of pollutants from any air condition in the surroundings.

ACH and CADR ratings:


The ACH range indicates you how many times the appliance can replace the air inside a room with clean, fresh air for every hour. It’s essential to understand that the ACH rating is straightly attached to the max square footage the air purifier can manage.
Generally, the ACH ratings in appliances are expressed in 3x, 4x, 6x, etc. The high rating proposes the device is highly effective in cleaning the air inside the room. We proposed that to purchase an air purifier with a rating of at least 6x if you have any asthma patients at home.


The main advantage of CADR rating is that it permits you to estimate how large a room the air purifier can manage evenly. This rating is particularly significant when you’re analyzing two or more air purifiers against each other and deciding to choose which one to purchase.
The CADR rating ensures that if an appliance requires to purify a range up to 300 sq. ft., which has been tested and verified being true. Additionally, it shows you precisely how well the appliance can get rid of particular kinds of indoor contaminants.


If you plan to use a particular air purifier for multiple rooms, we highly suggested that you need to select the lightweight device. Moreover, it is ideal to have a device with castor wheels or rollers and carrying handle for easy portability.

Noise level:

Concerning the noise level of an air purifier is essential, mainly if you’re going to utilize it in a bedroom or living room. Generally, air purifiers using the Ionization technique or UV technique comes without fans, and those are remarkably silent. Moreover, several types of air purifiers come with a fan speed adjustment option. So, ensure that your air purifier has such a setting so that you can operate the fan speed at least point to reduce the sound levels.

Programmable timer:

This automatic shut off the device after a particular time interval, such as 2, 4, or 8 hours. This feature improves to save power and prevents the device from continuous working while you’re not at home.

Digital controls:

The digital control options provide more specific settings for air quality control related to a rotary dial or push switch design.

Choosing the right filtration technology:

Filters are the most significant crucial guidelines for choosing an air purifier. Purifiers are designed with different types of filters to clean air pollutions from indoor.
These four air purification filters target various types of indoor air pollution and, we’ll explain specifically how each one operates.

HEPA filter:

High-Efficiency Particulate Air or HEPA filtration process is a well-known technology being used in different types of purifiers for many years. HEPA Filter contains fiber mats, foam, fiberglass, or cotton, which confines particles as the air crosses by them and, the performance of these filters depends on its diameter and thickness.

A good HEPA filter is permitted to remove more than 99.97% of all the tiny particles, still if they are as small as 0.3 microns. These HEPA filters are used to remove pollutants such as pollen, mold spores, fungi, dust, pet dander, hair, mold spores, and visible smoke.

Ionic filter:

This air purification technology works by releasing a cloud of charged ions into the air that locks upon airborne contaminants. This process makes these contaminations to fall over the floor and nearby surfaces. The main benefit of the ionic filter is that it can trap ultra-fine particles of small size 0.01 microns.

They are frequently washable and do not require a replacement for a very long time. This ionic filter removes dust, pollen, mold spores, volatile organic compounds, fungi, different bacteria’s and viruses, also visible smoke.

Activated carbon filter:

The activated carbon filters have a very particular form of carbon-containing with millions of tiny pores, and these pores are very absorbent. As it contains numerous pores, so the surface area is particularly large, this confines all the fumes, gases, and odors inherently.

Carbon filters are not only used to eliminate particles, but also used to absorb smelly particles and gases. These filters are most distinctly used to remove plenty of dangerous pollutants like smoke, chlorine, sediment, pesticides, herbicides, VOCs, and odors. These carbon filters are what make indoor smells fresh and clean.

Photocatalytic Filter:

Many air purifiers and air conditioners come with a photocatalytic filter. Photocatalytic Oxidation (PCO) filter utilizes a titanium dioxide metal plate that comes with UV light to oxidize and physically splitting chemicals through the filtration process.
These filters do not confine the contaminants in their original form.

They transform the dangerous organic pollutants into harmless carbon dioxide and water molecules, thereby effectively converting the toxic chemicals.

Maintenance tips:

Just like electrical appliances, air purifier also needs frequent maintenance for optimal performance. Here, we gave some tips that might help you.
• Always turn off and unplug the air purifier before moving or cleaning the unit.
• Ensure your air purifier has an indicator so that you are alerted to replace the filters as and if required.
• Clean washable pre-filters frequently, and make sure it is thoroughly dry before you place it back.
• The purifier requires sufficient places for taking in and releasing air for optimal performance. Ensure that the air purifier not placed in a confined space within furniture and wall.
• Similar to an air conditioner, lock all windows and doors before you turn on the air purifier so that it is not over-burdened uselessly.
• Keep the space clean nearby the purifier so that it can operate on purifying the allergens rather than the dust nearby the air purifier.
• Switch off the purifier, when you are cleaning the room or if there is any carpentry work, purifiers will get obstructed very quickly.
• In case the air purifier starts to release odor, remove the HEPA filter and activated carbon filter, then put it in the sun for sanitizing it.
