Keep your home free from dander and allergies with the best air purifier for pets

The streamlined and cylindrical Blueair Blue Max 3250i Smart WiFi Air Purifier is smart, powerful and stylish. It has unique HEPASilent™ technology that cleans air faster and with less noise than a H13 HEPA filter. It quickly cleans air: 20m sq in 12.5 minutes or 48m sq in 30 minutes, plus there's a particle sensor to measure the fine particles in the air. Four layers of filtration provide advanced pollutant removal that reduces pollen, pet dander, dust, bacteria/viruses, VOC, chemicals, smoke, dust mite matter, mould allergens, and cooking odours. An LED indicator displays the air quality through a colour indicator and the outer pre-filter is a removable fabric that's available in a range of colours, so you can customise this unit to complement your décor.

Tested by Commercial Content Writer, Natalie Knowles: "This Blueair air purifier makes big claims about its ability to detect pollutants in the air and safely filter them. Yes, on the first go it absolutely improved the air quality. It produced fresh, chilled air and circulated it around the room. Dust was significantly reduced. On a sunny day with it on the Boost setting, I could literally see motes of dust floating across the room towards the unit. On a low setting, it's barely audible at 18dB, while on settings 2 and 3 it's like white noise, at a maximum 46dB.

"It was extremely easy to set up the app and connect the air purifier via Wi-Fi and Bluetooth. I'm fascinated by the real-time air quality analysis. Also, I can control the fan speed via my phone or voice assistant. It immediately responds to any change in the settings. I'm very impressed with the ease and seamlessness of it after having a so-called smart coffee machine that was anything but!

"Now, it really blew my socks off for a couple of reasons. First, its ability to remove odour. By sheer accident, I'd put too much laundry detergent in the washing machine and the fragrance was mightily strong. Within a couple of minutes on Boost, this Blue Max 3250i had got the pungent smell under control. Next, is its ability to detect vapour and clean it. Just as a bit of an experiment, my partner used his vape beside the unit. My goodness, it went red within seconds. I was gobsmacked. Quickly looking at the Blueair app gave me real-time analytics on how long it would take to clean the air. But, it actually removed the vapour much faster because I had it set on Boost.

"As someone who knows how debilitating allergies can be, this Blueair is an absolute game-changer. It's smart, stylish and easy to use – plus, its ability to vacuum the air is astonishing. If you are combatting pet hair, dander and strong odours, I recommend this large Blueair model."

Combat canine cologne with the Shark NeverChange5 Air Purifier. The filter has a five-year lifespan – that's 10 times longer than a standard air filter. It comes with an odour neutraliser, so it's a great choice for a household with pets. There's a timer to adjust how long you want it to run and you can turn the lights off with Night mode.

Online reviews say that all the parts feel sturdy and the dust filter easily pops out so it can be cleaned. It's quiet running, silent on the lowest setting but quite loud on the highest setting (there are five settings).

On the display, overall PMi tells you how big the particles are in the air. It's actually powerful enough to removes smoke if food burns in the kitchen.

It's a tower fan plus so much more. The Dyson Purifier Cool™ Gen1 TP10 purifying fan contains a HEPA filter and carbon filter to enhance your home's air quality. Air gets sucked in, filtered and expelled as clean air. It has sensors that can continuously monitor air quality and the display shows particle levels in the air and even the types of particulates. However, there are no smart features with this model as it does not connect to Wi-Fi. It is operated by a remote control that can stick to the fan by magnetism. If you lose the remote control, you'll need to buy a replacement as there are no button controls on the fan itself.

Online reviews praise this Dyson Purifier for being a quality, sturdy build with parts that neatly click together. It is audible on the higher settings but it's a general white noise and it's very quiet below power level six. Choose from pre-set run times or activate continuous monitoring.

If you're concerned about maintaining a clean and healthy indoor environment this is a top choice. The Bosch Air 4000 Air Purifier removes 99.9 per cent of pollutants, including dust, allergens and other harmful particles. It has an air quality sensor that requires cleaning every few months. The display is more basic than the Shark and Dyson models which some users may prefer. A ring of light indicates the air quality. Also, it has a 1.6-metre power cable which gives more scope for positioning than a shorter lead.

Customers praise this Bosch air purifier for being quiet-running and lightweight to move around. It's effective in reducing pet odour. Reviews also say that the night mode is silent and there's no illumination to affect sleep. Another review comments that it lacks smart functionality; it doesn't connect to Wi-Fi or an app. While some will see this as a shortcoming, others may prefer the simplicity.

Another common comment amongst reviews is about cleaning the removable HEPA filter. Some customers have prolonged the lifespan of the filter by taking it outside and cleaning it.

The Philips 800 Series Air Purifier boasts a high CADR (Clean Air Delivery Rate). It can clean the air in a room up to 49m sq in just 16 minutes. Added to that, it has a low power consumption, using just 20W on maximum. Its sensor is fine-tuned to detect the air quality and it has a NanoProtect HEPA filter that captures particles down to 0.003 microns (smaller than the smallest known virus). It's quiet-running unless it's on Turbo, which swiftly but audibly cleans the air in the room.

This is a number one best seller on Amazon, with over 1,740 reviews rating it 4.6 out of 5. Customers praise it for being extremely lightweight and effective at reducing dust in the air. Some reviews go as far as to say that it halved the dust in their household.

A customer commented that they found the automatic mode a bit erratic as it would randomly switch from the minimum to maximum speed. But this might be due to its very sensitive sensor that is reacting to changes in the air, such as cooking fumes or smoke.

Ideal for a home office or small bedroom, this compact air purifier is powerful enough to pick up dust and other allergens before they have a chance to settle. It purifies the air in a 17m sq space in 30 minutes. Plus, it has an aroma pad that allows you to add a few drops of essential oil so you can scent your home.

The LEVOIT Air Purifier Core Mini has a top and bottom section that opens to reveal the removable filter. The upper section contains the motor and control panel. It automatically dims its display after one minute, so while it doesn't have night mode – it is not lit either – and it's whisper quiet at just 25dB. Do bear in mind the higher settings are audible, between 44-54dB. It is cheap to run as it only consumes 7W—that's minimal in comparison to a kettle, for example, which can use 3000W. Like most air purifiers it has a three-stage filter. The pre-filter captures large particles, such as dust and pet hair. This prevents them from clogging the HEPA filter, which captures fine dust, dander, pollen and smoke particles. The activated carbon filter physically absorbs odour and fumes and helps to neutralise smoke.

The downsides are that it doesn't have any advanced features and it's slower than other air purifiers in cleaning the air. In a smoke box test, it took a minute to clear the air on its highest setting. In addition, this means it's not as effective in neutralising odour.

Customer reviews indicate that this is a great air purifier to improve the air quality (and cool it) during the night. It's helped people to sleep better. So, while it's not as effective as other air purifiers for CADR, it's a generally good unit for improving wellbeing and cutting down on dust.

The CONOPU Air Purifier is a good budget option. It's small and portable and it can be moved from room to room. At 22W it's economical to run and there's a timer function if you prefer to limit its run-time. Unlike other air purifiers, it has top and bottom blue LED lights (that can be turned off) to create a relaxing ambience. Used in conjunction with its fragrance pad, you can create a relaxing ambience.

It has three-stage filtration and can change the air five times an hour in a medium-sized room. It's a great choice if you want a compact air purifier that has some aesthetic functions. Plus, it's a very reasonable price.

The CONOPU Air Purifier is an Amazon's Choice recommended with over 5,375 reviews rating it 4.3 out of 5. Customers praise the unit for reducing the amount of dust around their homes and helping to alleviate allergies. The only criticism is that some reviews comment that it's noisier than expected.

If you're looking for a cutting-edge device that can reduce pet dander, odours and allergens, the LEVOIT Smart HEPA Air Purifier is a brilliant option. It's compact and powerful, with advanced features including app control. The smart technology includes an air quality sensor, air quality indicator and auto mode. It draws in air through the vents on the front panel and the openings on the sides. Air is filtered and exits through the grill on the top of the unit. Unusually, this has a large rectangular filter. The washable pre-filter doesn't need replacing, while the HEPA filter can last up to a year. In addition, the activated carbon filter, which absorbs odours, will need replacing once or twice a year.

It has a slightly higher wattage than the other air purifiers, at 35W (which is still economical). Its noise range is from 40.5dB to 65.4dB on maximum, which is equivalent to a person talking. Whilst on auto mode or sleep mode it is silent. Also, its coverage is 20m sq.

It's an Amazon's Choice recommended product, with over 15,440 reviews rating LEVOIT 4.7 out of 5. Customers highly praise the effectiveness of this air purifier. It's helped people with lung disease improve their symptoms. The air sensor can rapidly detect changes in air quality, for example, cigarette smoke. Whilst it is a higher price point than other air purifiers, reviews say it's been well worth the money. The only quibble is that it requires replacement filters, and some people found that to be costly.

Make the air a bit more pleasant with the QUEENTY Air Purifier. It's small and compact – with two fan speeds – making it ideal for a desktop. It takes air in through the vents in the body and expels clean air through the fan head. It releases negative ions to help reduce allergic symptoms by attaching to airborne particles and removing them from the air. This small unit is intended for rooms 10m sq in size. It can oscillate 38° or rotate 360° to circulate clean air faster. It's extremely energy efficient, using just 2W of power. Also, it's whisper quiet at less than 35dB.

The HEPA filter needs to be replaced every six months. Twist to unlock and remove the filter. It has three-stage filtration: including a pre-filter, a true HEPA filter and an activated carbon filter.

Customer reviews are positive about its effectiveness as a small air purifier. However, some have been disappointed with its performance as a fan. Do bear in mind it is primarily for reducing allergens in the air; the cooling benefit is secondary.

The Blueair Blue Pure 511 is the smaller cousin to the Blueair Blue Max 3250i Smart WiFi Air Purifier. The unique Blueair filter technology helps to reduce pet and pollen allergy symptoms as well as having holistic benefits, including improving your skin, sleep quality and wellbeing. It takes in air from all directions, so while it's a compact unit, it still has a large filtration surface. It has a fast CADR (Clean Air Delivery Rate), purifying a 16m sq room in 12.5 minutes or a 38m sq room in 30 minutes. This helps to remove particles from the air, including smoke, pollen and bacteria that can trigger allergic reactions.

The removable fabric layer is the first stage of filtration, trapping hair and larger dust particles. There are five fabric pre-filter colours to choose from, all neutral and Scandi stylish. Use the Blueair app or control panel to select from five modes: auto, night and three-speed settings. The app will also tell you the remaining lifespan of the filter and when it needs replacing.

Tested by Commercial Content Writer, Natalie Knowles: "It may be small, the size of a table lamp, but this Blueair Blue Pure 511 is really powerful. I tested the Max model as well and the fan size on this smaller unit is comparable. The only feature it lacks is a light indicator to show the air quality, but you could monitor that through the Blueair app.

"It came with clear and well-designed instructions that showed how to operate the air purifier, connect it to the Blueair app, replace the inner filter and wash the pre-filter.

"I checked my electricity usage whilst running the air purifier and it hardly made a difference. I'd say this smaller model is best suited to small and medium-sized rooms. Also, it provides a wonderful cooling breeze on a hot day. I use it a night too and the constant supply of fresh, cool air helps me sleep better and reduces my congestion that's caused by allergies.

"All-in-all, this air purifier is ideal for a home office or bedroom. It's really quiet, effective and inconspicuous."
