Air purifier for home | how it works

The air in your home is not the same as the air outside. Inhaling this type of indoor air can have long-term effects on your health, from allergies to asthma to respiratory problems. A quality air purifier can help you live a healthier life by reducing indoor pollution and removing unwanted odors in your home. With this whole article, you will get some idea about Air purifier for home and how it works.

There are four major types of air purifiers: whole-home, room, portable, and electronic. Each type has its pros and cons. The right one for you will depend on how much living space you have and what kind of environment you prefer. Read on to learn about the different types of purifiers and which category might best suit your needs.

What Is An Air Purifier?

Unlike a typical air filter, an air purifier is designed to remove allergens, irritants, and other contaminants from the air. Purifiers also make your indoor air healthier by eliminating unwanted odors from pets, smoke from cigarettes, cooking, and other household odors.

Air purifiers work by drawing in dirty indoor air and passing it through a filter that removes particles in the air. The clean air is then released into your room or space.

There are a number of different types of filters a purifier can use to remove particles in the air. The type of filter will depend on what you are trying to remove from the air.

For example, if you want to get rid of odors in your home, an odor filter would be the best option. On the other hand, if you have allergies or asthma, an allergy or asthma filter would be best for you.

The Different Types of Purifiers


If you have a large living space with multiple rooms, then a whole-home purifier is the best choice for you. These purifiers filter the air throughout the home, which is important for people with allergies.

Whole-home purifiers can be expensive, but they are worth it if you have a large living space. And if you have pets, whole-home purifiers are the best option because they help filter pet dander.


If you are more of a minimalist, then room air purifiers are your best bet. These purifiers are often less expensive and are more of a temporary solution for pollution.


A portable air purifier is great for people with allergies or asthma who are constantly on the go. You can also use this type of purifier if your home doesn’t have central air.


This type of purifier doesn’t have any physical filtration. Instead, it works by releasing negative ions into the air. Electronic purifiers are often expensive, but they are good for people with allergies or asthma who need to control the specific allergens they are exposed to.

What is a Whole-Home Purifier?

A whole-house air purifier is the best solution for the largest living spaces. These are often installed in the furnace room or basement. They are expensive but are often more effective at cleaning the air, especially for people with allergies or respiratory problems.

A whole-house purifier has an air-cleaning system that can be customized to match your needs, but this type of purifier is best for large living spaces. It is typically more expensive than other types of purifiers, but it can be effective for people with allergies or respiratory problems.

What is a Room Purifier?

A room purifier is a type of purifier that can clean the air in a specific area, typically smaller than a whole-home purifier. The smallest room purifiers can typically clean the air in a room up to 150 square feet.

There are two types of room purifiers: those that attach to the wall and those without a permanent installation.

Non-wall-mounted purifiers may be more discreet and easier to move or transport than their wall-mounted counterparts. They can also be more cost-effective if you need to purchase multiple units, as they typically cost less.

What is a Portable Purifier?

A portable purifier is a compact machine that you can use to purify the air in rooms. The size of the machine varies greatly, and the filters usually need to be replaced every 3-12 months.

A portable air purifier is a good choice if you live in a small apartment or condo. They’re also helpful for people who don’t want to filter the air in their whole home. They can be very affordable and can easily be moved from room to room. The downside of a portable purifier is that the air quality might not be as good as a whole-home unit.

What is an Electronic Purifier?

An electronic purifier is a machine that works to remove specific impurities from the air. While they may not be as effective as other types of purifiers, they work well for small spaces. As the name suggests, an electronic purifier uses an electronic process to clean the air.

This process can vary from a variety of things, such as a fan that pushes the air, a filter system, or a combination of both. Some of these purifiers also use UV light to sanitize the area and remove bacteria. Electronic purifiers work in a variety of settings, from a room to a car.

In terms of effectiveness, electronic purifiers are the least powerful type, but they’re easy to use and can be very affordable. If you have a small space or want a machine that’s easy to move from room to room, an electronic purifier may be the right choice for you. With this, we hope you got some idea on Air purifier for home and how it works.

How to Pick the Right Type of Air Purifier for You

The type of air purifier you need is based on the size of the space you are looking to purify.

Portable air purifiers are designed to be carried from room to room. They are ideal for people who live in small, single-room homes and want a quality air purifier without the need for installation.

Room air purifiers are the most popular and the most economical option. They come in a variety of sizes and can be used in one room or multiple rooms. Whole-home air purifiers are built to clean the air in an entire house, but they can be pricey and difficult to maintain. Electronic air purifiers use ozone or ultraviolet light to kill bacteria and viruses that get into your air.

Whichever type you choose, make sure to do your research and find the right match for your needs.
