Buying Guide

When it comes to picking a new air purifier, there are several critical factors to consider. However, not all of these factors have equal weight. Specifically for large-room air purifiers, the following details are critical:

CADR rating

In simple terms, the clean air delivery rate, or CADR, is a measure of how quickly and effectively an air purifier can remove airborne contaminants. We use cubic feet per minute (cfm) or cubic meters per hour (m 3/hour) to measure it. With a higher CADR rating, you'll be able to run your fan at a quicker speed, which will result in cleaner air and a larger area covered. As an example, a 200 CADR air purifier can quickly clean a 100 sq ft room compared to a 100 CADR air purifier. In a separate post, I go into greater detail on this topic.

Power consumption

Air purifiers that are designed for large rooms typically require powerful fans. You should constantly evaluate the power consumption of different air purifiers to ensure that you are getting the best value for your money. If you don't keep track of the long-term costs, they might pile up quickly. Smart mode air purifiers come in help here because they automatically regulate the speed of the fan in real time (cost-effective).

Noise levels

There are a number of factors that influence the noise level of an air purifier. When the fan is running at full power, the noise can be extremely audible. A large room air purifier may require this information depending on where you intend to place it. To ensure that the noise won't annoy you in the future, always monitor the noise levels. You may read more about air purifiers and noise levels in a different blog article here.

True HEPA filter

First, let's take a look at the most visible part of an air purifier, shall we? An air purifier's true HEPA filter is a must-have component. With 99.97 percent accuracy, it can remove 99.97 percent of the dirt and contaminants from the air with a particle size of 0.3 microns. If you want to know if a device has this feature, you have to look at its name. Air purifiers that claim to have a "true HEPA filter" are the only ones you should put your trust in. Allergens, dust, bacteria, mold spores, and more can all be removed from the air using these filters. Asthma and other respiratory disorders can be triggered by particles in the air, and this function can help alleviate some of those symptoms.

Activated carbon filter

In order to remove all toxins from the air, it's necessary to use a HEPA filter that has been proven to be effective. In order to capture more polluted particles than a real HEPA filter is capable of, you'll need a more significant aid. A real HEPA air purifier with an activated carbon filter is recommended. These particles can be removed from the atmosphere by using this method. However, if you're using a real HEPA filter, you won't remove the cigarette's smell. This is where an activated carbon filter comes in handy; it removes any lingering smoke odors to ensure a thorough cleaning. Using this carbon-activated filter, you can eliminate flammable gases, dangerous substances, and odors.

In addition, this is the only filter capable of removing VOCs, or Volatile Organic Compounds, which are common in our indoor air. Through anything, even paint and cleaning agents, they can get in.


In order to maximize the performance of air purifiers, ionizers are used to increase the air purifiers' efficiency. Filters' lifespans and durability are improved as a result of the addition of this material. The air purifier goes through a lengthy process of discharging negative ions into the air and charging the particles it encounters. After that, the particles are immediately sucked into the filters, where they fall out of reach of your lungs and don't adhere to the environment. This isn't a requirement for an air purifier, but it's nice to have if you want to cover a larger area with your purifier.

Size and capacity – it’s coverage area

Choosing the best air purifier for your needs depends on the size of the room you're seeking to purify. According to the size of the room, most air purifiers can be rated for (for example, 900 square feet.) Choose a device based on your requirements.

Air changes per hour are used to measure the capability of air purifiers. The more air changes the gadget does every hour, the greater its capacity. Be aware that this simply takes into account the rate at which each molecule of air travels through the air purifier, and does not take into account the purification efficiency.

The features

Consider the additional characteristics that may be useful to you before purchasing an air purifier. Whether or not you have a smart home, do you need a smart air purifier? Is it possible for you to utilize your smartphone to change the way it works? Are you concerned about reducing your carbon footprint (3)? When it comes to noise, how sensitive are you?

Make sure you get a device that has the characteristics that are important to you and meet the requirements of your home because each one has advantages and disadvantages.
