How To Use Philips Air Purifier

[Rita Seliba]

Iuninstalled pycrypto and then edited the requirements to be pycryptodome (which is a more up to date forked version of pycrypto that appears to include the Crypto.Util.Padding module) in the philips_airpurifier/manifest.json file (see below), When the home assistant is stopped I deleted the philips_airpurifier/__pycache__ directory too. When restarted I now have access to the air purifier!

out of interest how did you verify the IP address the purifier had? I reserved the only device that had a Philips manufacturer MAC address in the DHCP setup of the router/service (not the purifier) to ensure it always got that address.

Edit: After some more packet capturing it seems 5683 is the coap protocal and it seems like it is communicating using coap also. Specifically when I first log on it requests the url coap://IPADDR/sys/dev/status. I tried some different coap clients ( -shell) but I cannot get an answer when I try manually it seems.

Shelly binding works fine for me.

However philips binding acting strange.

I can send commands to the thing but it takes a long time.

I do not see the status of the things. When I command ON, the status changes to ON, the thing turns on, but after that the status goes back to unknown.

If I restart the binding, it stays in offline mode, error message: init takes longer then 5s.

Thanks for the update and sorry for this late reply.

I reinstalled all three features and rebooted but the thing remained UNINITIALIZED.

I saw that the binding no longer appeared as installed, probably already before the feature reinstall.

I used the snapshot-3.2.0.jar binding from Marcel to link a AC2939/10 in openhab 3.3.0.

Placed the jar in the usr/share/openhab/addon and did not use the binding from the marketplace. This way the binding stays present after a reboot.

I created the thing manual in the main ui and did not used the auto discover thing, that one throws errors after a reboot. A key and device ID is not required during manual configuration.

As already mentioned above

Some dependency was not met and had to also install:

feature:install openhab-runtime-base

And:

feature:install openhab-transport-coap

feature:install openhab-transport-upnp

* From the air that passes through the filter, it is a theoretical time for one-time cleaning calculated by dividing its Clean Air Delivery Rate (CADR) 520 /h by the room size of 48 (assuming the room is 20 in floor area and 2.4 m in height).

Philips Air Purifiers actively monitor and clean the air in your home by trapping 99.97% of particles* that pass through the filter. They remove the most common allergens, including mold spores, pollen, dust mites and pet dander.

Using the CleanHome+ App you can control your air purifier anywhere, anytime. Check the air quality in the app to get reassurance wherever you are, and to compare your indoor air quality with the outdoor air quality.

I am trying to silence my air purifier (Philips AC5659/10). I think it uses a piezo-buzzer (front & back of PCB visible on page 4 of this document). In a similar vein to this question, I would like to know if it's safe to just remove the disc, leaving the inside of the buzzer disconnected?

I did this with my toaster oven because it was ear splitting loud. Unplug the device, take a flat head screw driver just pry it a bit at the bottom of the black cylinder. If it's anything like my piezo was, and they look very similar, it's a plastic cylindrical cap on top of a plastic tube base that houses a piezo disc inside. The cap popped right of and I took the disc out essentially leaving an open circuit in its place. Wasn't even glued in place.

Everybody has the right to clean air. That's why the innovation behind Philips Air Purifiers empowers you to free your home from harmful viruses, allergens and pollutants, ensuring better health for you and your family.*

Second, the NanoProtect HEPA filter captures 99.97%* of particles like fine dust and aerosols, as small as 0.003 micron. The synthetic fibers of the HEPA filter have an electrostatic charge that attracts and captures even the smallest particles just like a magnet.

Philips air purifiers remove up to 99.9% of aerosols from the air that pass through the filter and contain viruses. The size of the SARS-CoV-2 virus is estimated to be 50 to 140 nanometers (nm). Philips HEPA filters can remove 99.97% of the particles with a size of up to 0.003μm * (corresponds to 3 nm), which is smaller than the smallest known virus **, from the air that passes through the filter, a similar performance is expected for SARS-CoV-2 aerosols.

As with the H1N1 virus, we have started working with renowned partners to prove the effectiveness of our air purifiers in removing coronavirus aerosols. Previously, through independent tests, Philips has proven that its air purifiers reduce the concentration of influenza A (H1N1) virus aerosols in the air passing through the filter by 99.9%.

The Lancet 2020, Vol 395, May 30th, e100 v *** Microbial Reduction Rate Test at Airmid Health group Ltd., which was carried out in a 28.5m3 test chamber contaminated with airborne influenza A (H1N1). An air purifier alone won't protect against COVID-19, according to the US Environmental Protection Agency, but it can be part of a plan to protect you and your family.

After the viruses are caught in the filter, they naturally become inactive. Depending on the ambient temperature, this can take anywhere from a few minutes to several hours. The viruses are unlikely to spread again from the filter.

Our HEPA filter has a high particle capacity and is designed to effectively capture particles as small as 0.003 microns that will be filtered over its lifetime. For best results, we recommend that consumers change the filter when it has reached the end of its life.

Philips air purifiers create a stream of air with a fan that draws the air through a HEPA filter. Our air purifiers have been proven to remove 99.97% of the particles in the air up to a size of 0.003μm * (corresponds to 3 nm) as well as particles such as bacteria, allergens, soot, dust and smoke from the air that passes through the filter.

As for the SARS-CoV-2 virus that causes COVID-19, the size of the SARS-CoV-2 virus is estimated to be 50 to 140 nanometers (nm).

Therefore, a separate air flow for measuring the performance of air purifiers is meaningless, it is unfiltered air. Only when you take into account how much air has been filtered can we name the amount of really clean air.

Since the outside environment is a critical factor in the indoor air, the same CADR could clean a larger room in countries with lower pollution levels. Therefore, different standards for calculating the room size have been created by different countries, which are tailored to the respective situation.

Philips Domestic Appliances is one of the global leaders in Air Purifiers, with a team of over 100 scientists, engineers and doctors working on air purification every day. Philips air purifiers create a stream of air with a fan that draws the air through a HEPA filter. Our air purifiers have been proven to remove 99.97% of the particles in the air up to a size of 0.003μm * (corresponds to 3 nm) as well as particles such as bacteria, allergens, soot, dust and smoke from the air that passes through the filter.

Philips Air purifiers remove up to 99.9% aerosols and viruses from the air. The HEPA filter present in Philips Air Purifiers captures 99.97% of ultra-fine particles as small as 0.003 microns, so you are safe from PM2.5, bacteria, pollen, dust, pet dander, gas and other pollutants. Outside Pollutants can sneak inside. With Philips Air Purifiers, you can breathe clean air inside your home.

The Philips Air Purifiers come with a digital Air Quality display, where you can see the Air Quality of your home in real time. You can see the level of allergens, gases and PM2.5 in numerical form, as well as an intuitive colour ring.

The Philips Air Purifiers are thoroughly tested for quality, with 170 mandatory and strict inspection tests. They are also tested for rigorous life and durability tests, for continuous operation 24/7.

**CADR= Clean Air Delivery Rate. CADR is the volume of filtered air given off by an air purifier. CADR measures the cubic meter of filtered air per hour, it is about the cleaning speed. Higher CADR is required in large sized rooms and the rooms where the pollution is high.
