Description

Standing tall upon the shoulders of giants (thank you [fLshX](https://www.crealitycloud.com/model-detail/seamless-bottom-integrated-filterbox-k2-plus?source=23) and [GreyFoxDesigns](https://www.crealitycloud.com/de/model-detail/k2-plus-ultimate-recirculating-hepa-filter)!), I present you **The Immaculate Air Filter** for Creality K2 Plus. This model is designed from scratch to provide a free, easy-to-build and reversible recirculating filter that removes VOCs, airborne particles and smell, keeping you healthy and your printer's warranty intact. The mod can either be used standalone or together with **[The Magnificent Air Duct](https://www.crealitycloud.com/de/model-detail/magnificent-air-duct-creality-k2-plus)** mod to create negative pressure and completely avoid any leaks from the chamber.

If you find this design useful, don't forget to like and boost it.

The Immaculate Air Filter has the following benefits:

- Large filtering volume.

- Inexpensive consumables that are widely available from Amazon, AliExpress or Ebay.

- Looks great.

- Low noise thanks to adjustable fan speed.

- Filters are easy to change.

- Easy to clean from dust and debris thanks to magnetically attached prefilters.

- The design is optimised for easy printing and low filament use.

- Easy to assemble.

- Protects your health by removing VOCs, airborne particles and smell while printing.

- Keeps heat inside the chamber - great for saving energy and maintaining a stable chamber temperature.

- Does not require a separate power supply.

- Does not permanently modify the printer - you can undo the mod if you need it.

- Does not interfere with the print bed.
