Bosch Air 2000 Review – Is It Worth the Price?

Full Review

Bosch is a premium and very well-known German brand primarily recognized for its durable, innovative, and high-quality household appliances.

This is my first time testing an air purifier from Bosch.

The Bosch Air 2000 is the smallest air purifier in Bosch’s series, but it’s very interesting, competitive with many air purifiers we’ve tested so far, and, most importantly, highly efficient.

In this article, I will focus on a detailed review of the performance, features, and specifications of this model, but I will also make a brief comparison with some similar models.

How We Tested the Bosch Air 2000?

1. For the filter efficiency testing, we used the Temtop LKC-1000S laser particle meter, which measures PM2.5 (µg/m3), PM10 (µg/m3), Particles (per/L), and HCHO (mg/m3) in the air, and also calculates the AQI.

2. We placed the Bosch Air 2000 in two separate performance tests, one in a 194 sq. ft. (18 m²) room and the other in a 320 sq. ft. (30 m²) room. Then, we recorded the initial air quality values using the Temtop laser particle meter and let the Bosch Air 2000 run at maximum speed.

3. After 60 minutes, we measured the new values using the Temtop laser particle meter and saved the data.

4. Next, we placed the Bosch Air 2000 in a glass box, which we then filled with smoke. Then, we measured how much time was needed for the air purifier to remove all the smoke from the box.

5. Using a special noise measurement tool, we tested the air purifier’s noise level at all speeds. We measured the noise level on the dBA scale.

6. Finally, we measured the power usage at all speeds using an energy meter, after which we calculated how much it would cost to use the device at a particular fan speed for one month. For reference, we used an energy price of $0.12 per kWh.

Before diving into the performance test results, I want to point out that this air purifier has a much lower CADR than I initially expected.

With a CADR of just 106 CFM (180 m³/h), it’s recommended for rooms up to 165 sq. ft. (15 m²).

Given its size, we tested it in two rooms of different dimensions.

The conclusion from our tests is that the Bosch Air 2000 is a highly efficient air purifier that delivered excellent results not only in a room of the recommended size but even in a slightly larger room.

Let’s take a look at the test results.

Testing in a 194 sq. ft. (18 m²) Room

In the first test, performed in a 194 sq. ft. (18 m²) room, the Bosch Air 2000 improved air quality by approximately 92% after just 60 minutes of work at maximum speed, which is a very good result.

It reduced the PM2.5 concentration from 100.9 to 7.3 µg/m³.

Compared to the competition (see chart), the Bosch Air 2000 ranks quite well. For example, the Levoit Core 300S improved air quality by 94% under the same conditions, while the Blueair 511i Max achieved a 92% improvement.

All in all, Bosch delivered an excellent result, earning it a spot among the top-performing air purifiers we’ve tested so far.

Testing in a 320 sq. ft. (30 m²) Room

In the second test, this time in a larger room than recommended, measuring 320 sq. ft. (30 m²), the Bosch Air 2000 also delivered a very good result.

After just 60 minutes of operation at maximum speed, it improved air quality by approximately 89%.

Given that the Bosch Air 2000 has a low CADR, it’s expected that it wouldn’t be too loud.

However, I was surprised by its noise at maximum speed, where it produced a noise level of 62.7 dBA. Compared to the competition, I must admit that there are quieter air purifiers available, some of which even offer higher CADR.

For example, the AEG AX5 is significantly quieter at max speed, generating just 56.8 dBA, while delivering a much higher CADR of 170 CFM (290 m³/h).

At lower speeds, the situation improves, and I must say that Bosch has done a great job optimizing the device. At the lowest speed, it produces just 40.1 dBA of noise.

All in all, while it may be slightly louder than the competition at maximum speed, I would still say the Bosch Air 2000 is overall well-optimized for noise and is definitely a device I would recommend for bedroom use.

The Bosch Air 2000 uses a 20W motor, making it a very well-optimized air purifier in terms of energy efficiency.

However, the issue is that, for this power level, it should ideally have a higher CADR, especially considering that there are many air purifiers on the market with higher CADR and similar or even lower power consumption.

For example, the Blueair 511i Max uses a motor of the same wattage but delivers a significantly higher CADR of 152 CFM (258 m³/h).

If you were to run the Bosch Air 2000 at maximum speed, 24 hours a day, for an entire month, your electricity bill would increase by only around $1.73.

As for the replacement filter, it’s slightly more expensive than those found in similarly priced air purifiers.

Therefore, even though the device uses a highly efficient motor, the slightly higher filter cost makes the Bosch Air 2000 less optimized in terms of annual maintenance expenses.

Filtration Technology

The Bosch Air 2000 uses a classic 3-in-1 HEPA filter, similar in design to the filters found in other cylindrical air purifiers.

The filter is located inside the bottom part of the device.

This air purifier doesn’t use an ionizer, UV light, or any additional filtration stages, meaning that all filtration relies entirely on the 3-in-1 filter.

Pre-filter

The first filtration stage is the pre-filter, which primarily captures large particles such as large dust, hair, pet hair, and similar.

This means that the pre-filter improves overall efficiency and protects and extends the lifespan of the HEPA filter.

The pre-filter is essentially a nylon mesh attached to the HEPA filter.

I recommend cleaning the pre-filter at least once or twice a month, or even more frequently if you’re using the air purifier in spaces with pets.

HEPA Filter

The core stage of filtration is the HEPA filter, which captures small airborne particles such as pollen, allergens, mold spores, bacteria, and viruses.

This stage is mainly responsible for the outstanding performance the Bosch Air 2000 demonstrated in our performance tests.

Activated Carbon Filter

The final stage of filtration is an activated carbon filter, which consists of carbon pellets.

Air purifiers that use carbon pellets instead of a fibrous filter coated with carbon are generally much more effective at neutralizing unpleasant odors.

I used the Bosch Air 2000 in my home for a while, and what I noticed is that, in addition to its excellent performance in capturing airborne particles, it also performed very well in neutralizing bad odors, especially lighter odors, rather than heavy or persistent ones.

How to Replace Bosch Air 2000 Filter?

The Bosch Air 2000 uses non-washable, non-reusable filters that need to be replaced when the time comes.

The filters typically last between 6 to 8 months, and when it’s time to replace them, you’ll be notified via the filter check indicator located on the control panel.

A potential issue some users have reported is the lack of available replacement filters. However, during the writing of this review, testing, and regular use of the Bosch Air 2000, I consistently checked the availability of replacement filters and didn’t see any shortages.

The filter replacement process is extremely simple.

Setup and Installation

Before you even use this air purifier, you have to do a simple preparation, which is contained in just a few steps.

First, you have to open the filter cover and pull it out of the device. Then, unwrap it from the plastic wrap, and place it back inside the device.

Now, your air purifier is ready to use, and everything you need to do is to place it in the desired location.

But, please make sure to move it from walls or other objects and not to block air inlets or outlets, as that could potentially damage the motor and lower the performance.

Design

Although the Bosch Air 2000 features a classic cylindrical design, I must say it still stands out from competing devices on the market.

The unit is primarily white with black accents, most prominently featured on the top section. What makes the design especially interesting is the slightly curved top part.

In addition, the plastic quality and overall build are excellent.

What I do miss, however, are handles for carrying the unit from room to room. Even though it’s a lightweight device, such an addition would make it much easier to move.

All things considered, I believe this is an outstanding air purifier that will fit well into almost any environment.

Display and Controls

The main controls, LED indicators, and display are located on the top of the device.

The touch buttons are well-arranged and highly responsive, and the LED indicators are clearly visible. There is also a display that shows the current PM2.5 particle concentration in the air.

It’s also worth noting that the Bosch Air 2000 remembers its last operating mode, meaning it will resume at the same speed it was running before being turned off.

Although the addition of a remote control option would have been a great addition, I must say I’m very pleased with the control panel design and functionality.

Airflow

The Bosch Air 2000 is a cylindrical air purifier with air intake openings positioned around the lower part of the device, allowing it to draw in air from all sides.

The air that enters through these vents is filtered and then released through the grilles located at the top of the unit.

Size and Dimensions

The Bosch Air 2000 has dimensions of 9.25 x 9.25 x 15.28 inches (23.5 x 23.5 x 38.8 cm) and weighs 4.96 lb (2.25 kg).

It’s not bulky and is a lightweight device, but I would still like it if it had carrying handles or slots.

What’s in the box?

When you buy the Bosch Air 2000 air purifier you will get 1x air purifier, 1x 3-in-1 HEPA filter, and user manual.

Features Overview

The Bosch Air 2000 belongs to the category of air purifiers that doesn’t work with a smart app, but it offers plenty of advanced features that are more than sufficient for everyday use.

Air Quality Sensor & Indicator

The Bosch Air 2000 uses an air quality sensor that detects PM2.5 particulate matter in real-time.

This sensor collects all the data it gets about the air quality and sends it to the air quality indicator, but it also correlates with the auto mode feature.

The air quality indicator is a ring around the top of the device that lights in the different color based on the current air quality. In the table below, you can easily see what color represents what.

Air quality light color	Air quality level	PM2.5 level
Blue	Good	0-12
Purple	Ok	13-35
Orange	Poor	36-55
Red	Bad	>56

However, there is also a display on the top of the device that shows the current PM2.5 particulate matter, which is a catchy feature and something that I miss on some competitive air purifiers.

You should keep in mind that the air quality indicator will show the real data 30 seconds or more after turning the device on and that you can also turn off the air quality indicator light if you want by holding the quiet mode button for about 3 seconds.

Auto Mode

Auto mode is another feature that works in combination with the air quality sensor.

When in auto mode, the air purifier will switch the fan speed based on the current air quality.

This means that if the air quality is bad in your place, the device will change the fan speed to higher, and if it gets better it will lower the fan speed.

In that way, it will keep the high performance and good air quality in your place.

When I use an air purifier, such as the Bosch Air 2000, which doesn’t offer a smart app feature, I always let it work for 10-15 minutes at the maximum speed, and then switch to auto mode. In that way, I do an initial cleaning of the air and then just maintain the air quality using auto mode.

Timer

Since this air purifier doesn’t have smart features, the timer function can be especially useful.

It allows you to set a specific time for the Bosch Air 2000 to automatically turn off.

You can set the timer anywhere between 1 and 12 hours.

Child Lock

The child lock is a feature that allows you to lock the control panel for accidentally pressing and changing the preset options.

It’s ideal if you have kids around and don’t want your set settings to change.

Quiet Mode

When in the quiet mode, the Bosch Air 2000 will switch to the lowest fan speed but will also dim all the LED lights.

Warranty

The Bosch Air 2000 air purifier comes with a 3-year warranty, which is more generous than what many air purifiers offer.
