Air purifiers on sale are great appliances to include in your home, but they're often rather pricey. Fortunately, we've shopped around and found the best deals so you can take advantage of these sales without wasting time searching the internet. 

The best air purifiers not only filter the air, but they sanitize it, too. You may be surprised to learn that a recent U.S. Environmental Protection Agency report found that indoor air can have up to five times higher levels of pollutants like mold, pesticides and particulates than the air outdoors. So, having a device in your home that removes these pollutants, as well as allergens like dust, pet dander and pollen, is a pragmatic, healthy choice. 

Things to consider when choosing an air purifier include the size of the area you want to filter, the space available for the appliance itself, and how quiet you'd like the device to be. With our roundup of these air purifier deals, there are several models and designs to choose from; that way, you're sure to find one to fit your needs and budget.

Which air purifier is right for you?

What air purifier you choose will likely depend on the size of your home and rooms, your budget, and your lifestyle (whether you have any pets, or if you're sensitive and allergic to dust and other particles).

The efficiency (and thus the price) of an air purifier is determined by its "clean air delivery rate", or CADR, which indicates how quickly and how much air it can clean in your room. When selecting a model, make sure the CADR is at least two-thirds the size of your room to ensure efficiency. Another useful measure is the ACH, or the "air changes per hour" - the higher that number is, the quicker will clean air be pumped back into your home.

Apart from these technical specifications, make sure to check how loud an air purifier is, as the noise can be disruptive if you run it in a bedroom. Additionally, some models emit light when they operate, which could disturb some light sleepers. The Honeywell HPA300 lets you dim its lights and automatically shuts off after a set amount of time, which is handy for use during the night.

Last but not least in your considerations, there is the matter of budget. Some high-end air purifiers such as the Dyson Purifier Cool cost just shy of $500, but you can get perfectly good options around the $100 mark like the Levoit H132. No matter what you're after, we've got something to suit your needs in our roundup of air purifier deals.

Honeywell HPA300 HEPA air purifier

Best for large rooms

Specifications
Filter type: True HEPA filter
Coverage: 465 sq ft
Noise: 63 dB
Modes: 4 – Allergen, General clean, Germ and Turbo
Reasons to buy
+Powerful+5 year warranty
Reasons to avoid
-Lacks smart features-Bulky and heavy

If you need a powerful purifier for a big room, the Honeywell HPA300 makes light work of microscopic matter and comes recommended by allergy experts. It uses three HEPA filters to screen smoke, dust and viruses and a carbon-activated pre-filter works to remove odors, gases and trap larger allergens such as pet dander and pollen. 

With four cleaning modes – including turbo to improve air quality faster, it's designed for large areas and is capable of five air changes an hour in a room size of 465 square feet. Although you can't operate it remotely, the unit's tap buttons are easy to navigate. It has an auto-shut-off timer, the controls panel's lights can be dimmed or turned off, and LED indicators tell you when it's time to replace the filters. 

Any drawbacks? It's by no means the quietest purifier on our list and weighing in at 17 lbs, it's also not the most portable. But, for ultra-effective filtration with a competitive price tag, the Honeywell HPA300 is exceptional value for money.

GermGuardian AC4825E air purifier

Best budget buy

Specifications
Filter type: HEPA filter
Coverage: 153 sq ft
Noise: 55 dB
Modes: 3 fan settings
Reasons to buy
+Portable+Effective for the price
Reasons to avoid
-Basic functions-Noisy at lowest setting

The GermGuardian AC4825E performs better than what you'd expect from a purifier priced under $100. This slimline, 3-speed tower weighs only 7lbs, so it's incredibly easy to move around your home. It freshens rooms up to 153 square feet with four air changes an hour and has good CADR ratings for a low-range model.

Along with an odor-destroying charcoal pre-filter and True HEPA filter that absorbs dust and allergens from pets and plants, this purifier uses a UV-C light bulb that works with TiO2 (Titanium Dioxide). This helps to protect against airborne germs, killing mold spores and viruses as they circulate in the air.

There's little in the way of extra features on the GermGuardian AC4825E apart from a LED filter replacement indicator, but if you're looking for a simple purifier to use in smaller-sized rooms, it's an excellent choice.

Dyson Purifier Cool air purifier

Best for smart functionality

Specifications
Filter type: HEPA H13 standard
Coverage: 201.5 sq ft
Noise: 61.5 dB
Modes: 3 – Auto, night and airflow direction
Reasons to buy
+Duel air purifier and fan+Iconic design
Reasons to avoid
-Limited CADR information-Expensive

The Dyson Purifier Cool is a stylish option that cools the air as it cleans. Yes, it's pricey, but there are plenty of smart features that justify the spend. 

Using Dyson's AirMultiplier technology, pollutants are sucked into the machine and a smooth stream of cooling, clean air is circulated into the room – with backwards airflow for when you don't need the fan. It features a glass fibre HEPA 13 filter that catches 99.95% of particles as tiny as 0.1 microns – everything from pollen and dust to bacteria and mold spores, and an activated carbon filter that removes harmful gases and smells. What's more, the entire purifier (not just the filter), is sealed to HEPA standards to prevent pollutants from escaping back into the air.

The tower oscillates at 360° so you can direct airflow with a choice of 10 settings, including auto-mode with a smart sensor that adjusts air quality. Sleep mode activates extra-quiet filtration and a dimmed display. Set up voice control with Amazon Alexa, Apple Siri or Google Home for hands-free use or connect and control via the Dyson app – data enthusiasts can also track real-time air quality and view previous stats on particulate matter and VOC levels in the home.

Coway AP 1512 HH air purifier

Best for asthma and allergy sufferers

Specifications
Filter type: True HEPA filter
Coverage: 350 sq ft
Noise: 53 dB
Modes: 5 – including auto and eco
Reasons to buy
+Compact +Quiet
Reasons to avoid
-Pre-filter requires frequent cleaning-Comes with only one carbon filter

The compact Coway AP 1512 HH has an effective 4-stage filtration system that provides noticeably purer air in rooms up to 361 square feet. There's a washable pre-filter to capture dust, pet fur and hair, and a carbon filter that removes harmful gases and odors. Common allergens are dealt with by the HEPA filter and it also has an ionizer (which can be switched on or off) which releases negative ions that Coway claims helps to clean the air.

Choose auto-mode and the fan speed self-adjusts to improve air quality, or you can manually cycle between three fan settings. Switching into eco mode makes the Coway AP 1512 HH one of the most energy-saving models on the market – saving you on energy bills.

Along with impressive CADR ratings and its great design, what we like about this purifier is that it's one of the quietest we've reviewed. On the lowest setting there's only 24 dB of noise, making it an ideal option for sleeping.

Winix 5500-2 deal

Winix 5500-2 air purifier

Best for ease of use

Specifications
Filter type: True HEPA filter
Coverage: 360 sq ft
Noise: 53 dB
Modes: 6 – including auto and sleep
Reasons to buy
+Effective in medium / large rooms+Remote control
Reasons to avoid
-No Wi-Fi connectivity-Only two year warranty

With CADR ratings to rival more expensive purifiers, the Winix 5500-2 has excellent air-cleaning performance in larger rooms – it can purify a 580 square foot space in just 20 minutes. Allergens are removed in four stages of filtration using a pre-filter, carbon filter, HEPA filter, and Winix's PlasmaWave Technology that disperses dual polarity ions to break down airborne bacteria, viruses and VOCs. 

The Winix 5500-2 has built-in smart sensors that detect the tiniest of particles and LED light indicators inform you on air quality so you can switch between the four fan speeds. We liked that the auto-function detects a change in light to turn on sleep mode – and there's a timer, too. Although the W5500-2 can't be operated via an app, it does have a remote control so settings can be changed from across the room.

You can expect to replace the HEPA filter around once every 12 months and an indicator reminds you. The bonus is that both the fine-mesh pre-filter and the carbon filter on this unit are washable, making it an economical option in the long-term.
