Buying Guides of the Best Large Room Air Purifiers

There are a series of factors or tips that we must look at when choosing an air purifier or another, depending on what our objectives are or what to use it for.


HEPA filters are in places that require good ventilation, such as airplanes, example or operating rooms so that all the air in these places previously passes through the filters. But they also have a more domestic use and are found in some purifiers thanks to the fact that it allows filtering more than 99% of the particles.

HEPA stands for High-Efficiency Particular Air and not all purifiers include these types of filters, certified and reliable. Some bet on “similar” filters so you should pay attention.

Room Size

It is important to take into account the size of the room that we need to “purify” because we will not need the same power in a 60-square-meter room as in a children’s room of, for example, 13 square meters (with their corresponding differences in cubic meters).

Both in other devices related to the air in the room, such as fans or purifiers, we must look at the size or the number of cubic meters to choose one that suits: that does not exceed or that we need but neither that does not come to purify everything completely.


To choose the best air purifier for your needs, consider the size of the room you want to purify. If you are allergic or asthmatic and are looking for an air purifier to help you manage and stabilize your symptoms, you should also consider your device’s air change rate per hour (CADR).

This rate is the number of times an air purifier can filter the entire volume of air in the room each hour.

Purifiers that can treat the air in a space at least four times per hour are best suited for people with allergies and asthma. A rate of four air changes per hour also ensures that the air purifier deeply cleanses the environment and filters out several microscopic symptom-triggering allergens to prevent seizures.


We must also look at the noise it makes since it will be a device that we will have on for many hours or that we will generally turn on at night.

The idea is that it purifies the air whenever we are at home so that we can breathe that cleaner air and we will not want to find an annoying and continuous noise that does not allow us to sleep or that does not allow us to listen to the television.

Air Analysis

Some air purifiers allow us to use an application or a screen that allows us to have an analysis of the air to know the quality of the air or the possible risks that we run until we “clean” it.

Will a Small Air Purifier Work in a Large Room?

This is also often what causes the prices to vary from one device to another. A low wattage purifier will not be effective in a room that is too large. Conversely, a device that is too powerful in a small room will probably seem too noisy to you.

Types of the Best Air Purifiers for Large Room

The best type of air purifier is not the same you want it to purify the air and reduce negative ions than having an allergy and you want that function to be the most developed.

HEPA filter air purifiers: Those who are more demanding or have strong allergies to any agent, can buy an air purifier with a HEPA filter, which usually retains even the smallest microns of dust while neutralizing aromas.

Ionizing air purifiers: In addition to filtering the air, they emit negative particles to counteract the positive particles that are emitted in our homes by electrical appliances, and the union of both makes them fall and can be vacuumed.

An air purifier with activated carbon filter: If you want a purifier that also eliminates bad odors, you must have an activated carbon filter. This is a system with a porous filter that retains odoriferous particles.

Air purifiers with ozone: it is not recommended for a house and at the domestic level (although you will find guides for its sale). Its control of this gas must be exhaustive as it is toxic from 0.3 parts per million and is the trigger for asthma attacks in susceptible patients. Ozone is a toxic gas either because it is generated directly or because it is the result of a chemical reaction in ionizers.


It will not hurt you, so if you have a budget, it is a function that you can look for that your purifier has, because something better the air seems to clean.

The use of the best air purifier that produces ozone can worsen the ambient air instead of improving it since the effectiveness of removing pollutants nitrogen dioxide or formaldehyde is low.
