The air in your home and workspace can be infiltrated with germs, dust, mold spores, pet dander, smoke, allergens, and other pollutants that can affect your health. While vacuuming often will help reduce the amount of dust in areas, it is not so great at removing those extra fine particles that it cannot pick up; in order to do this, and improve your air quality, you require an air purifier.

Your large rooms may be harboring these airborne particles that are damaging to your health. Air purifiers work by cleansing your air, drawing dirty air in, removing and cleansing the particles you won't want to be breathing in, providing you with clean air; they are unlike humidifiers, which add particles into the air. The majority of air purifiers feature a filtration system to trap particles as the air moves through them, whereas some air purifiers can neutralize these particles without requiring a filter.

Cleaner air benefits us all, but especially those who suffer from conditions like asthma or have allergies. If you suffer from allergies or have asthma, you will notice a reduction in symptoms if you use your air purifiers frequently, as it will help remove allergens, pet dander, and dust, the main culprits behind your condition.

So, which are the best air purifiers for large rooms? This guide will help you determine the best air purifier for your large room and help you identify some key features you need to consider prior to any purchase you may make. Let's get started!

Features To Consider With Air Purifiers For Large Rooms

Size

When you are shopping for the best air purifiers for large rooms, you will want to consider the size of the purifier itself. Purifiers designed for larger rooms tend to be larger and more robust, yet powerful and durable, in appearance they are quite similar to portable air conditioners. If you are wanting to be able to move your air purifier between rooms, you should consider features that will make it easily portable like wheels and handles; or, it will need to be a manageable weight and size to move easily. Many air purifiers are designed with the modern home in mind, so even though they may be bulkier, they tend to fit well into most spaces. Some units offer customizable panels, so you can be sure it suits wherever you plan to use it.

Noise Level

Noise level is an important feature to consider when looking for air purifiers, especially if you are a light sleeper or if you are planning to use them in office spaces or living areas. Sound is measured in a unit called decibels (dB); normal conversation is typically about 60 dB, so when looking at the best air purifiers for large rooms, you can use that as a comparison. A whisper is 30 dB and the majority of air purifiers operate at this level or lower when in sleep mode. Most air purifiers are loud when on their highest setting as the fan needs to move faster to circulate the air quickly, but with lower speed fan options or sleep mode, you can be assured of a peaceful night's sleep or a successful meeting with no interruptions from a loud air purifier.

best air purifiers for large rooms

Connectivity

If you want to be able to connect your air purifier to your Wi-Fi connection, it will need to be Wi-Fi enabled. Wi-Fi connectivity allows you to remotely control your air purifier from your smartphone. You are then typically able to connect a smart home system, like Amazon Alexa, for voice commands. This is a great feature if you are on the go frequently and need to be able to adjust and control settings from your phone, whether you are home or not!

Filters

The types of filters used within the filtration system of the best air purifiers are an important consideration, to ensure that your air quality is as clean as possible. The best air purifier will feature a True HEPA air filter, which will remove up to 99.97% of airborne pollutants and particles, as small as 0.3 microns. A HEPA filter is able to capture up to 99% of particles 2 microns or larger. Pre-filters are great for initially filtering the air and capturing larger particles; normally, pre-filters are washable, so these do not require replacements. Another filter that can be found in the best large room air purifiers is an activated carbon filter, which removes unwanted odors in your home, such as smoke and volatile organic compounds (VOCs). It's very efficient, but you still need a carbon monoxide detector if you want to know the exact level of CO in your house.

air-purifier-for-large-room-filter

Air Quality Monitor

If you want to be able to see the current quality of your air in real-time, an air purifier would need to include an air quality monitor. The quality of the air is typically displayed either as an LED colored ring, with different colors indicating how clean the air is; alternatively, some use an actual reading. This is a great feature that allows you to see what kinds of things you could be doing that add pollutants to your air that could be harmful to your health. Most air purifiers that have an air quality monitor also will include an auto mode, which will detect the cleanliness of the air and adjust the fan speed as necessary - the cleaner the air, the slower the fan will run, the dirtier the air, the faster the fan will run; this is great for hands-free control, so you can get on with your busy day without worrying about needing to adjust settings. In case your air purifier doesn't have an air quality detector you don't have to worry, you can purchase a specialized air quality monitor as an addition to your air purifier. You can also get a dehumidifier, to maintain the perfect air humidity level in the room.

Room Size

Room size is a crucial factor you need to bear in mind prior to purchasing any air purifiers. All air purifiers will have information about the square footage they cover; it is important to consider the square feet of the large room, or if you have high ceilings, you are wanting to use the air purifier in. If you purchase one that is too small, it will not work well and won't provide effective cleaning. Many air purifiers will speak of their air changes per hour and this is based on the maximum square footage they cover - you will never achieve this if your air purifier is too small for the room in which it is placed. You will notice that many air purifiers speak of clean air delivery rate (CADR), which measures the cubic feet of air filtered per minute; so, the larger the space you are needing an air purifier for, the greater the CADR required to provide effective air cleaning.

best-large-room-air-purifiers

Maintenance

To ensure that your air purifier is running at its highest performance, you will need to make sure that the filters are kept clean and replaced when they are dirty. The best air purifiers will have a filter replacement indicator of some sort that will draw your attention to when the filters require replacing. The downside to air purifiers is that the HEPA filters and activated carbon filters require replacing several times a year and there is a recurring cost associated with this. Most pre-filters are washable, so you can use a vacuum or a damp cloth to clean it of dirt and debris that it has collected before fitting it back into the unit. Ease of access to the filters is also a consideration so that you do not need to worry about moving it and fiddling with doors and entry points that may be in places that are harder to access, depending on where you have it positioned.

Other Features

The point at which air intake occurs is also something that you should consider before buying an air purifier; first of all, consider where you would be positioning it in your home, if it needs to be flush against a wall, you will want to find a purifier that features air intake from the top or front of the unit. Some air purifiers offer 360-degree air intake, so it is a good idea to make sure they have adequate space all around when positioning them.

The option of a timer is a good feature, especially if your air purifier does not have Wi-Fi connectivity, sleep, or auto mode that allows for easy control. Being able to set a timer for an air purifier to run constantly at your preferred setting is great if you will be out for a few hours at a time, or perhaps sleeping and you don't want to be disturbed by the fan increasing in speed if it detected a change in the air.

Air purifiers that do not have HEPA filters can emit ozone into the air; however, there are some air purifiers that can create ozone if they have ionizing features. There are some air purifiers that have optional ionizing features or UV C lights, which are great at accelerating air purification but can emit ozone. So, if you suffer from allergies, asthma, or have a chronic obstructive pulmonary disease (COPD), you should always look for an air purifier that is ozone free.

Air Purifier For Large Rooms FAQ

Q: Can an air purifier be too big for a room?

A:

While there is not necessarily anything wrong with using an air purifier that is too large for a room, per se, it is not entirely efficient to do so. If you do use an air purifier that is too big for a room, it will be too powerful, which can end up costing you more money than you needed to spend. If you have bought an air purifier that covers a much larger area than you are wanting to use it in, you can open the door to create a larger area for it to purify air effectively.

Q: Do you need an air purifier for every room?

A:

Realistically, most people do not use an air purifier in every room. Instead, they would choose the most popular rooms, like living areas, offices, and bedrooms, to place their air purifiers.

best large room air purifiers

Q: How long does it take an air purifier to clean a large room?

A:

This is entirely dependent on the fan speed and the size of the large room you are using the air purifier in. In general, most air purifiers can take anywhere between 30 minutes to 2 hours to go through one cycle of air; however, you can begin to notice results in as little as 10 minutes with some units. By making sure that you buy an air purifier that is suitable for the size of the room you are placing it, the air changes per hour will be as per the advertised figure when used on the highest setting - generally once or twice per hour.
