I work on a clone of the blueair 503 for a while now, and have succeeded to reach my goals.
Goals where:
– Easy to DIY, maintain and repair
– Cheaper than original (that was the easy part)
– Address a few shortcoming of the 503 (price being the first thing to be addressed 😉
-Being safe and look good
– Being sleep friendly
You can have a look at the box design here, you will find also a pdf with all the measure needed to create your own.

When i am sure of the final design i will post the bill of material and a tutorial for setup.
Keep u posted!
