CleanR
Description
# CleanR CleanR is a DIY air purifier project. **Goal** of the project is to create an air purifier which is cheaper and more silent than the commercially available ones. **You can find the details, progress, source, stepfile, schematics and sw here: [GitHub](https://github.com/Levente96/CleanR)** ## Components Current revision is based on the following components: * NF-A14 industrialPPC-24V-3000 Q100 IP67 PWM * Random HEPA filter(*should not matter as long as it works*) * 3D printed case(*see resources*) * USB-C power input * DC-DC step-up module ## Assembly  ## Perforamnce The goal is to beat the following performance: > 320m^3/h (recommended for up to 106m^2) of air for ~100$ with 31-61dB(A) Simplifying this means you got 3m^3/h for each m^2 which means you are paying '~1$/m^2'. Our performance is the following: > 260m^3/h (according to Noctua specs) with up to 41dB(A) of noise Calculating the "optimal" m^2 for this device would be 86 m^2 which is still larger than I need, for around 1/3-rd of the cost. This design is **2.59 times** more value ($/cleaned air) than the Xiaomi Air Purifier 3C. ## Cost The goal of all time to keep the cost under ~100$. Currently it costs: | Item | Cost | | ---- | ---: | | Fan | 33$ | | Filter | 3$ | | DC Converter | 1$ | | Connector + cables | <1$| | 3D printed box | ~3$ | | ESP-01 | 1$ | | 1K ohm resistor| <1$ | | TIP122 | <1$ | | **Total:** | **42$** | ## Roadmap * `v1.0`: Simplest version, with no other optioans than plugged in and running, and poweroff state :heavy_check_mark: * `v2.0`: ESP8266 built-in for controlling the fan-speed according to preprogrammed timestamps :heavy_check_mark: * `v3.0`: Basic web interface :heavy_check_mark: , OTA :heavy_check_mark: , redesign * `v4.0`: Mesh network of these devices with standalone air quality measurement point
