This instructable is about using nature to purify your air. It is based on the ANDREA air purifier. This product is quite controversial, as a lot of people think it doesn't work. But the technology of using a plant as an airfilter is really cool. So we decided to make a less fancy one ourselves to test the technology.

Step 1: Collect Parts

We wanted to recycle leftover materials where possible, so most parts are gathered from our workshop. The only parts we bought are the plant and a sieve. So the shopping list is:

An airpurifying plant (in our case the Hedera Helix, but an Aloe Vera plant would also work)
Multiplex wood 5mm (at least 310x380 mm)
Multiplex wood 12mm (at least 120x160 mm)
Perspex 5mm (120x300)
A 12 V 0.23 A computer fan (we used one with a 85 mm diameter)
An old modem adapter
A plate to attach the ventilator
A metal grill plate (0.5 mm thick)
A metal kitchen sieve
A carton soup container (diameter: 90 mm, height: 100 mm)
Wood glue
Double sided tape
6 small screws.
2 super small screws.

Step 2: Saw the Wood and Perspex

Start with sawing all the wood pieces and the perspex plate.

We created the hole for the ventilator using a sharp drafting compass and a chisel. But a big hole drill would be way faster ;)

Step 3: Build the Box

Glue the wooden attachment strips on the sides of the ventilator hole (on the outside)
Glue the wooden attachment blocks 10.5 cm from the top to the side plates. (on the inside)
Tape the side panels to the bottom, using the double sided tape
Tape the perspex plate in between the sides and to the attachment blocks, using the double sided tape
Put the back plate on the back and drill a hole through the back plate and in the each of the attachment blocks and in the bottom.
Screw the back plate using these holes.

Step 4: Build the Ventilator and Put in on the Box

Cut off the plug for the modem adapter
Connect the wires to the ventilator wires in such a way that the ventilaor sucks
Screw the ventilator on the connection plate
Drill the attachment strips
Attach the ventilator to the box

Step 5: Make the Pot and Ad the Plant

Cut the metal grill plate
Fold the metal grill plate
Open the sieve
Cut and fold the sieve so that it fits in the folded grill plate
Put some wet dirt on the bottom of the pot so that the dirt doesn't fall straight through
Put the plant in the pot

Step 6: Insert a Water Basket, an Air Tunnel and the Pot

Cut the top of the carton soup basket
Tape this cut off part over the ventilator
Insert the bottom part of this soup basket as a water container
Insert the pot so that it fits on the attachement blocks and voila it is done!

Step 7: Enjoy a Nice Potter and Ventilator and Hopefully Fresher Air

Hopefully it will work and the air will actually be purfied. Otherwise it is quite a nice potter/ventilator combination. As soon as we can get our hands on a testing device we will see if the product will really make the air better. We'll keep you up-to-date!

Good luck and a lot of fun making it!
