Making a combined humidifier and air purifier

Hello, dear readers and self-made people!
Almost every one of you is faced with polluted air every day in your apartment, office, or other small rooms. Even if you live in an ecologically clean area, it has little effect on the amount of “household” dust in the air.
In this article, the author of the YouTube channel “DIY YARI” will tell you how you can make an effective air purifier combined with a humidifier.
The fact that this device can increase the humidity in the room will be very useful during the heating season. This model uses the natural evaporation scheme.
Making a combined humidifier and air purifier This project quite easy to manufacture, and can be repeated at home.
The design of the purifier-humidifier is very versatile, and it can be done without using a 3D printer.
Materials required for homemade products.
– Regulated power supply
– Quiet fan ARCTIC
– Filters for a Philips air humidifier
– PETg Filament for 3D printing Almazok
Tools and devices used by the author.
– Dremel, dremel attachments
– Creality Ender 3 3D printer
– Air monitor.
Manufacturing process.

Making a combined humidifier and air purifier Of course, there are a huge number of different air purifiers, for example, such an advanced model as Xiaomi purifier 3 .
In addition to the rather high cost of the purifier itself, a lot of money will have to be paid for filters that need to be changed every 2-3 months.
Moreover, this model independently checks the presence of dust in the air, and starts cleaning. But the detector is tuned for very small particles, so to remove large dust particles, you need to turn it on for forced cleaning.
With all the electronic “bells and whistles” – such cleaners are nothing more than a case, a quiet fan, and a group of filters.
 Making a combined humidifier and air purifier Making a combined humidifier and air purifier Making a combined humidifier and air purifier For the first prototype of a homemade cleaner, the master purchased a plastic basket with holes in the walls and a lid for it.
A large hole is made in the lid for air, and four small holes for attaching the fan.

The power supply with voltage regulation was chosen by the master only to select the optimal speed, and check the noise level. In principle, a simple 12V power supply is enough for this fan, unless there will be an opportunity to reduce the speed.
The fan is fixed on the cover with four screws, and for now is installed to blow air into the case.

This is one of the mistakes that can be made when designing an air purifier. The filter must always be “in front” of the fan. So already purified air will pass through the fan, and dust will not accumulate on the blades.
Making a combined humidifier and air purifier As a result the fan was turned 180 degrees, and the filter mesh was fixed directly to its frame.

Making a combined humidifier and air purifier Making a combined humidifier and air purifier Before production the second, improved version, the master also thought about the need to humidify the air, which is especially important in the cold season.
Simple humidifiers today most often work on the principle of ultrasonic generation of “steam” – the smallest droplets of water. Such devices will produce a jet of steam regardless of the humidity level in the room.
Of course there is models with a built-in air humidity sensor.
One of the problems of such humidifiers is the need to fill exclusively with distilled water, otherwise all surfaces will be covered with a white layer of minerals.

In a recent article , the master has already talked about the creation of such a humidifier.
This model is not bad, but the case for it is somewhat complicated to manufacture.
These types of humidifiers are devoid of the above-described disadvantages.

In fact, it is a plastic case with a water tank and an additional replaceable mesh evaporator.

One such filter will cost 200 rubles, but it is reusable and can be washed.
 Making a combined humidifier and air purifier You will also need the same quiet fan and regulated power supply .
 Making a combined humidifier and air purifier Already many masters use 3D printers everywhere, and design models for their devices.
The author has created a 3D model in the Fusion360 software package (I also master it and recommend it to everyone).
Making a combined humidifier and air purifier  Making a combined humidifier and air purifier Since his own printer was not available to the master (at the moment he is in another country), he turned to local 3D printers to print the models. To his surprise, the price for a 120-gram model was almost equal to the cost of a 3D printer.
As a result, a Ender 3 3D printer was purchased – an excellent model that prints out of the box with dignity. This printer is assembled in an hour and a half.
The exact same model has been working for me for six months. For the price of two good screwdrivers, you get your own CNC machine for the production of plastic parts.

3D models can be downloaded at link courtesy of the author.

The frame itself can be made from another smaller bucket, having drilled many holes in it. So you can do without a 3D printer.

As you can see, everything works fine.

As already mentioned, mesh the filter can be reused to wash away the accumulated dust.
