Best Air Purifiers for the Bedroom

Since 2020, I’ve bought and tested 134 air purifiers (and counting!) to separate the good units from the absolute scams. The good news is that improving the air quality inside your home doesn’t need to burn a hole in your pocket.

1. Best for most bedrooms: Levoit Vital 200S

A high-performing air purifier with smart functions and cleaning power that matches units sold for double its price.

The Levoit Vital 200S is the air purifier I recommend for the bedroom for most people. And a big reason why that’s the case is the fact that you can buy it for less than $200 and it has all the features you would need such as a light sensor that automatically engages the sleep mode when it detects it is night.

It also also offers excellent value, with enough CADR (clean air delivery rate) to clean medium sized rooms well at top and sub-45 dB speeds and pretty low running costs.

Plus, it comes with an onboard sensor, auto mode and one of the best apps I’ve tested, with new smart features being rolled out regularly.

One big benefit for those looking to use it in the bedroom is the fact that you can customize the sleep mode via the Vesync app. I recommend that most people look to adjust their sleep mode to run at either speed 1 or 2 as the default sleep mode is often too weak for most bedroom sizes.

When it comes to performance, the Vital 200S, completed our particle removal test in 24 minutes, matching the newer Winix 5510 and outperforming the popular Blueair 311i Max. However, unlike those two units, the Vital 200S doesn’t have an ionizer.

Based on this result, we estimate a PM1 CADR of 249 cfm, which will be powerful enough to provide five air changes per hour in bedrooms no larger than 360 sq. ft.

It comes with a bonded filter with a pleated particle filter (for pollen and dust) on one side and a pelleted activated carbon filter (for odors and gases)on the other.

In addition to a bonded particle and gas filter, the 200S comes with a pre-filter that can be removed to be vacuumed and/or washed to extend the life of the filter. This is super useful for those with pets that generate a lot of larger hair particles.

CONS

• The carbon and particle filters are bonded, so once the carbon becomes full (within 6-12 months), you will need to replace the entire filter.
• The particle filter is not HEPA grade, even though Levoit initially advertised it as H13 HEPA. This doesn’t affect performance.
• Its air quality sensor is infrared, so it needs to be cleaned periodically to stay accurate.

PROS

• It offers great performance for an air purifier under $200.
• The filter has pelleted activated carbon, which is better than carbon-impregnated fabric.
• It comes with auto mode and app support with the VeSync app and the option to customize sleep mode
• You can remove the pre-filter for easy cleaning.
• It doesn’t use an ionizer, so it is ozone-free.
• It is relatively quiet — it hits 57.7 dBA at its top speed, and its performance at speed 2 (41.9 dBA) is very good.

2. Best for Large Bedrooms: Blueair Blue Signature

A high-CADR air purifier that doubles as a table and comes with a laser sensor and app support.

The BlueAir Large Signature looks like a piece of furniture and also doubles as one so could make a great bedroom side table. It has a wide table surface on top, and you can even add legs to lift it off the ground. It’s currently the most powerful air purifier table I’ve tested.

Whilst this model is the largest in the range, there are also now two more signature edition models:

The smallest model is the series is the Blueair Signature Small, there is also the Blueair Signature Medium SP3i which sits between this model and the small and has a CADR of around 300 cfm.

CONS

• It is more expensive to buy and run than other table air purifiers from IKEA and SwitchBot.
• There is no option to disable the electrostatic ionization function, unlike what we see from other manufacturers like Winix, Coway and Xiaomi.
• The wooden legs and the chrome base to turn it into a table are not included, so you’d need to pay up to $100 more to elevate your Blue Signature.

PROS

• It doubles as a side table that will fit most living rooms and bedrooms – you can even buy legs to give it more height.
• It matches the air cleaning performance of high-end units that cost twice its price and are twice its size.
• It comes with a laser sensor on board that is highly accurate and doesn’t need to be cleaned regularly.
• The Blueair app has a clean UX and is easy to use.
• You can customize the design with multiple pre-filter fabric colors and two leg design options.

3. Best for Small Bedroom: Alen Breathsmart 35i

The best sounding air purifier to our ears with a laser sensor and options for custom filters

The Alen BreatheSmart 35i is quieter at top speed than every other small air purifiers we have bench-marked it against. Running on speed 2 it still had enough power for 5 air changes per hour in rooms up to 163 sq ft.

The Alen 35i is part of the BreatheSmart range that includes the larger Alen 75i and Alen 45i which if you like the design of the 35i but need more power these could good models to check out. If you do want smaller then the Alen 25i is the smallest version although you will lose some of the power at higher fan speeds that you get with the 35i.

Alen states that the sound output is pink noise which has been shown to be easier on the ears which is something that can be very useful when using an air purifier in the bedroom.

The laser sensor inside makes the auto-mode more responsive, more accurate and more useful than what you’ll get with other small air purifiers.

Alen offers a choice of 3 filters when you buy from Pure (Medical HEPA only), Advanced (includes pelleted carbon) and Ultimate (also includes a proprietary carbon catalyst designed for odors.)

Finally Alen has a lifetime warranty as long as you only buy Alen filters or have an active filter subscription.

You get to choose the right tool for the job in the form of three specialized filters:

• The Pure filter, which is a HEPA H13 filter without any carbon so good for allergens and dust.
• Then there’s the Fresh filter, which combines HEPA H13 with a half-pound layer of activated carbon to capture both particles AND gases.

And lastly you get the Odor filter, which combines HEPA H13 with activated carbon treated with Alen’s odor-neutralizing compound to help deal with smells more easily than carbon alone.

Like the larger BreatheSmart models, the Alen 35i has an AHAM CADR report available on the EnergyStar website and was certified in 2025. Their report gives it a dust CADR of 164 cfm.

For context, that means that, for allergy sufferers seeking the recommended 5 air changes per hour, you could use this device in a room up to 246 square feet.

It cleaned the room in 36 minutes, and accounting for the natural ventilation of our test room, we estimate a PM1 CADR of 162 cfm.

That’s a good time – a few minutes faster than the Coway Airmega 150 and the Levoit Vital 100S, and a massive jump over the popular Shark NeverChange HP150.

CONS

• High initial price compared to its performance.
• For the same price, you can get a mid-sized air purifier from brands like Levoit and Coway.
• Filter replacement costs are also higher than those of other brands, so you will spend more in the long run, too.

PROS

• At top speed, it’s quieter than similarly sized models, without losing air cleaning power.
• It comes with a high-end laser sensor, which makes the auto mode genuinely useful.
• The Alen app works well and provides real-time PM2.5 data as well as tVOCs and CO2 levels.
• Build quality is high, from the filter seal to the power supply – – and it comes with a lifetime warranty.

4. Best value for money: AirFanta 3Pro

If you care about one thing — maximum air cleaning at the minimum price — the 3Pro is untouchable.

The AirFanta 3Pro is a PC fan-powered air purifier that broke the mold. Based on our tests, we estimate a PM1 CADR of 353 cfm, which is incredible considering its low price of $159.99. This makes the 3Pro capable of providing five air changes per hour in rooms up to 529 sq. ft.

CONS

• The design is not for everyone, with a subscriber describing it to me as “a sci-fi toaster”.
• It has no smart features, no air quality sensor, and no app support.
• It’s in high demand, so it is often out of stock on Amazon. If you can’t find it on Amazon, check the official AirFanta shop.
• You will have to build it yourself, but it takes just a couple of minutes to do so.

PROS

• It offers the best performance for $ spent across the 130+ air purifiers we tested.
• It is the only high-CADR air purifier you can fit in a backpack.
• The use of PC fans makes it quieter and more energy-efficient than most traditional retail air purifiers.
• It comes with an AC-to-DC power adapter that includes a dial to adjust the voltage and sound levels.
• You can choose between HEPA-only or HEPA with activated carbon. If you need to tackle odors or VOCs, get the filters with carbon.

5. Best quiet: CleanAirKits Luggable XL Ultra

The XL Ultra offers the best performance-to-noise ratio with the lowest long-term running costs.

The Luggable XL Ultra is an air purifier you can build yourself, with seven PC fans and two HVAC filters, resulting in an estimated PM1 CADR of 315 cfm with a sound level below 48 decibels! That means this air purifier can clean the air five times per hour in rooms up to 472.5 sq. ft.

CONS

• The lightweight wood looks great, but the body is more delicate than plastic or metal you’ll find in other air purifiers. If durability is a concern, check out the cherry wood Aerating End Table.
• It doesn’t come with carbon, so it won’t help with odors and chemical gases.
• It’s a large device that won’t fit in smaller spaces. But if you like the look of the Luggable, then you can choose the 5-fan version.
• It doesn’t come with any smart functions or app support.

PROS

• It offers excellent air cleaning power even under the 45 dBA limit we set for quiet performance tests (284 cfm).
• You can use any brand of 20×25 MERV 13 filters, which leads to lower running costs.
• It’s lightweight and comes with a handle for easy movement from room to room.
• The body is made of lightweight wood, making it more sustainable than traditional plastic air cleaners.
• You can buy the DIY kit, which is cheaper and includes everything you need to build it at home (except the filters).
• If anything breaks, you will be able to fix it yourself.
