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!
