You can find a number of air purifiers on sale at the moment — but which ones are really going to make a difference to the air in your home? At Live Science we’ve tested a number of the best air purifiers over the years, so we’ve put together our pick of the devices that are really worth buying on sale.

Air purifiers can be a great addition to your home, but they often come with a hefty price tag. That’s why air purifiers on sale offer the perfect opportunity to invest in one of these appliances, with discounts on top models.

Air purifiers help to filter the air in your home, with a U.S. Environmental Protection Agency report finding that indoor air can have up to five times higher levels of pollutants like mold, pesticides and particulates than the air outdoors. For those with respiratory issues such as asthma or allergies, these handy devices can make all the difference as they work hard to remove dust, pet dander and pollen, as well as other pollutants.

With our round-up of these air purifiers on sale, there are several models and designs to choose from, so you’re sure to find one that fits 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.

Air purifiers on sale

Honeywell HPA300 HEPA deal

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 deal

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 deal

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 deal

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.
