If you’re currently shopping for Black Friday air purifier deals, but you’re feeling overwhelmed with the choices, we’ve got all the information and offers for you. Alternatively, if you're looking for more in-depth reviews and insights from an expert, then head over to our guide to the best air purifiers. 

These Black Friday air purifier deals will help you and your family breathe better, as they remove pollutants in the air. Poor air quality can cause an array of health problems - from ongoing allergies and respiratory problems to headaches and irritation of the eyes, nose and throat. And while most of us worry about the pollution outdoors as recorded by the Air Quality Index, according to the Environmental Protection Agency (EPA) the levels of pollution inside our own homes can be two to five times higher. 

Contaminants in the air could include everyday household pollutants, including pollen, dust, pet hair and dander (microscopic flecks of animal skin) and smoke. Other pollutants include mold on walls, bacterias and volatile organic compounds (VOCs) - which can sometimes be found in household cleaners. 

Since the pandemic and the spread of COVID-19, many of us are more aware of the air we breathe - meaning air purifiers have become more popular, in a bid to kill off viruses in the air and help with allergies. If you’re looking at the higher end of the marker, take a look at our guide to the best Dyson air purifier deals right now.

View DealWhich air purifier is right for you?

Before you think about buying a Black Friday air purifier on sale you might be wondering - how do air purifiers work? Every air purifier is measured by its clean air delivery rate (CADR) - which indicates how quickly and the volume of air it can clean in your room.

As a minimum the CADR rating should be two-thirds of the room size when it comes to cleaning pollutants such as dust and pet dander - of course, the higher the rating, the better the performance. When looking at how well it purifies the air make sure you check its air changes per hour (ACH) rating too  - it means how quickly the certain model can change the air in your room - a higher rating means fresh, healthier air is pumped into your room at a faster rate.

One important aspect of the air purifier is the filter - as this will help to ‘filter’ the pollutants out of the air. The highest standard filter is a high-efficiency particulate air (HEPA) filter - as they are 99.7 percent effective at filtering out pollutants, as small as 0.3 microns. 

Of course, 100 percent of pollutants in the home can’t be removed by air purifiers - so making sure you keep a clean house and tackle any mold, as well as letting clean air into your home is also advised. Many people buy air purifiers to help with allergy symptoms - if you’re looking for one to help clear your stuffy nose or irritated throat make sure it captures pollen and allergens effectively. Other factors to consider when buying an air purifier are its different cleaning modes, how much noise they emit and how portable they are.

Cost is also a big deal breaker too. If you’re looking for an air purifier, such as some of the models by Dyson, you should be prepared for costs of $500 and above, while a budget model could save you money - spending around $100. Of course, there are always great air purifier deals, across even the most well-performing and expensive models on the market. 

Air purifiers on saleHoneywell HPA300 HEPA deal

(Image credit: Honeywell)Honeywell HPA300 HEPA air purifierBest for large roomsSpecificationsFilter type: True HEPA filterCoverage: 465 sq ftNoise: 63 dBModes: 4 – Allergen, General clean, Germ and TurboReasons to buy+Powerful+5 year warrantyReasons 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.

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.

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.

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.

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.
