Eoleaf vs. Philips air purifiers

Here at Eoleaf, we have delved into the pros and cons of Dyson air purifiers at length. What about other market leaders? Philips, one of the world’s largest multinational electronics conglomerates present in over 100 countries, is heavily present on the air purification market. How do Philips air purifiers hold up to Eoleaf air purifiers? Read on to learn more below.

Performance

The most important question for us is: how well does a device combat indoor air pollution? When it comes to your health, spending hundreds of pounds on a device with insufficient filtration capabilities is simply not worth the risk. Read on to find out why the Philips 2000i series is comparable to Eoleaf’s AEROPRO 40 and why the AEROPRO 40 is more powerful.

Philips’ 2000i series air purifier vs. Eoleaf’s AEROPRO 40 air purifier

Philips’ 2000i series air purifier: CADR

The most important metric to consider during device comparisons is Clean Air Delivery Rate (CADR). This air rate metric is used to allow customers to compare air purifier efficiency in eliminating air pollutants between brands. The higher the CADR, the more efficient the device is.

According to their website, Philips’ 2000i series offers a CADR of 330 m3/h and covers a room size of up to 79m2. However, there seems to be a critical error in Philips’ air rate calculations. In order to calculate the volume of air in a space that can be treated by an air purifier, the formula is as follows:

• Volume (of the room in m3) = CADR/ACH
• ACH
• ACH refers to ‘air changes per hour’ and is the number of times that air in a room or space is completely removed and replaced in an hour
• The industry standard for ACH is set at 4 or 5 in order for an air purifier to be considered effective

• Using the values given by Philips for its 2000i series and the above formula, the room volume capable of being treated by the 2000i series would be, considering the minimum industry standard for ACH of 4:
• Volume (m3) = 330 / 4
• Volume (m3) = 83.25

Although this is not far off from the 79m2 they indicate on their website, the 83.25 calculated above is, in fact, volume (m3), not surface area (m2). To calculate surface area, we must use the following formula:

• Surface area (m2) = CADR/(ACHx2.4)
• 2.4 refers to the average ceiling height in the UK (in metres)
• Again, using the minimum industry standard for ACH of 4 in the above equation:
• Surface area (m2) = 330/(4x2.4)
• Surface area (m2) = 34.68

That said, it seems that Philips made a mistake in indicating the surface area capable of being treated by their 2000i series air purifier. This device’s air rate only allows filtration of the air in spaces of 34m2, no larger. Considering the low price of this device of £400 (429.99€), this seems fairly logical; however, it is marketed for ‘large spaces’, which, in reality, is certainly not feasible. The Philips 2000i is comparable to our AEROPRO 40, the smallest model in our range that covers spaces up to 40m2.

If we compare the CADRs of Philips devices (see table below), we conclude that Eoleaf's smallest device (the AEOROPRO 40) actually compares more closely to the Philips 3000i:

Generally speaking, Philips devices are less powerful than Eoleaf devices and appear not to meet industry sizing standards (which recommend 4 to 5 ACH or Air Changes per Hour).

Eoleaf’s AEROPRO 40 air purifier: CADR

As mentioned in the Philips CADR section above, it makes more sense to compare the Philips’ 2000i series with our AEROPRO 40 device rather than the AEROPRO 100 (seeing as the 2000i series filters the air in spaces of up to 34m2 and the AEROPRO 40 filters the air in spaces of up to 40m2). Our AEROPRO 40 device boasts a significantly higher CADR compared to that of the Philips air purifier 2000i series: 420 m3/h. This impressive air rate makes it ideal for small spaces for all consumers, both individual and professionals alike.

Eoleaf devices continue to stand out regarding air rate/purification efficiency (CADR) and air quality improvements.

Philips’ 2000i series air purifier: filtration technologies

Most of the big air purifier brands offer one or two air filtration technologies and not much more. The Philips air purifier 2000i series is no exception. This device comes equipped with a pre-filter for coarse particles, a HEPA filter (H13) for fine particles, and an activated carbon filter for odours and chemical pollution (VOCs). These are indeed effective but fairly standard technologies which do not remove all forms of pollution. In order for an air purifier to remove the most basic air pollutants, it should contain at least a HEPA filter and an activated carbon filter. HEPA filters (H13-certified) remove 99.97% of all air pollutants down to a size of 0.3 microns (including allergens, most viruses and bacteria, and fine particles), but in reality, they are capable of filtering particles that are much smaller (down to 0.01 microns or even smaller): read more about the 0.3 micron barrier here.

The germ question

It is worth noting that this Philips air purifier lacks UVC sterilisation technologies. This an extremely useful technology in professional spaces like medical institutions and doctors’ offices due to its ability to combat airborne viruses and bacteria. This technology was essential during the COVID-19 pandemic in helping to reduce transmission of airborne viruses. However, UVC sterilisation does more than that: a device without some form of sterilisation technologies cannot sterilise the filter(s). A filter’s goal is to trap pollutants, including germs. It is not enough to simply capture germs: once they have been captured, they must be destroyed. Destroying the germs minimises the risk, even when a device continues to be used with a saturated filter (a practice we strongly recommend avoiding), of re-entering your indoor environment. Destroying germs also prevents your device from becoming a pathogen breeding ground. Philips devices do not contain any form of sterilisation technologies; Eoleaf devices, on the other hand, use UVC lamps placed at the very centre of the cylindrical filter in order to allow sterilisation in every corner.

The Philips 2000i series air purifier also offers a PM2.5 particle air quality sensor.

Eoleaf’s AEROPRO 40 air purifier: filtration technologies

All of Eoleaf’s home and office air purifiers offer 8 different air purification technologies as part of our multi-layer filtration technology. This includes the technologies offered by the Philips 2000i series and more. Our devices include:

• Pre-filters
• Bamboo filters with an antibacterial coating
• Medical-grade HEPA filters (H13)
• Activated carbon filters
• UVC sterilisation technologies (two 254 nm UV lamps), useful for the removal of viruses (including viruses caused by the common cold and COVID-19) and bacteria
• Photocatalysis technologies (20 million pcs/cm3)
• Ionisation technologies (negative ions)

Our air purifier performance, again, blows the Philips 2000i series out of the water, with our devices removing 99.97% of all air pollutants down to 0.01 microns (including allergens, viruses and bacteria, and fine particles) in a single pass. 

Philips’ 2000i series air purifier: vertical output

We were pleased to find that the Philips air purifier 2000i series offers vertical output. Many of the leading air purifiers on the market (notably Dyson’s) offer horizontal output, meaning that purified air is diffused from the device back into the room in a horizontal fashion. This makes it difficult to achieve proper placement for your device since the purified air will be obstructed by any and every furnishing present in the home (couches, beds, shelving, furniture, etc). A vertical output ejects the purified air upwards (vertically), encouraging optimal air mixing.

Eoleaf’s AEROPRO 40 air purifier: vertical output

Like the Philips 2000i series, Eoleaf air purifiers all offer a vertical output for optimal indoor air quality improvements. As mentioned above, this is extremely important in ensuring clean air mixing for all consumers, individual and professional spaces alike.

Usability and connectivity

Philips’ 2000i series air purifier

Regarding usability and connectivity, the Philips 2000i series air purifier is quite comparable to Eoleaf’s AEROPRO 40.

The Philips 2000i series offers features like Automatic mode, Sleep mode, and Night settings, as well as four fan speeds. It also offers some smart features like Wi-Fi and smartphone compatibility (Air+ app), and voice control. It is a bit larger than Eoleaf’s AEROPRO 40 but still fairly comparable, measuring at 32.6 cm (diameter) x 53.5 cm (height) (see AEROPRO 40 dimensions below).

Eoleaf’s AEROPRO 40 air purifier

Eoleaf devices equally offer all of the above features to consumers: Automatic mode, Sleep mode, smart features like Wi-Fi and smartphone compatibility (Tuya Smart app), and voice control. The AEROPRO 40 measures 27.5 cm (diameter) x 54.2 cm (height) and offers four fan speeds (1-2-3-4).

A few details differentiate Eoleaf air purifiers from Philips’ 2000i series:

• Our devices offer gesture control (for hands-free use)
• Eoleaf air purifiers offer either handles or wheels, encouraging easy portability if the device needs to be moved to a different room (particularly useful in professional spaces); portability is not specified for Philips’ 2000i series
• Eoleaf air purifiers can be automated using smart scenario features

These few differences make Eoleaf air purifiers a bit more intuitive, modern, and user-friendly.

Maintenance and warranty

Philips’ 2000i series air purifier

The Philips 2000i series air purifier is again quite comparable with Eoleaf’s AEROPRO 40 when it comes to maintenance. Filters require changing once every year on average in order to ensure clean air.

The biggest difference between the Philips 2000i series and the AEROPRO 40 lies in its warranty: Philips air purifiers only offer a 2-year limited warranty compared to Eoleaf’s 3-year warranty.

Eoleaf’s AEROPRO 40 air purifier

Similarly to Philips’ 2000i series, the AEROPRO 40 requires annual filter changes. All of Eoleaf’s 8 filtration technologies are located within one filter block, making for easy filter changes that can be performed by anyone. No need to remember separate filter schedules for your separate HEPA filters and activated carbon filters – it all gets replaced at the same time!

As mentioned above, all of Eoleaf’s devices are covered by a 3-year warranty. The longer the warranty, the more trust a company has in the durability of its own products.
