The Battery operated air purifier is simply to freshen up small rooms that lack air conditioning . Although this is about one cubic foot and weighs about three to 4 pounds.Testing to see how well it works was with a grove dust sensor and the air purifier halved the concentration of particles in the air . The testing was done in a closed environment and data that came as result of outside influence is exempt.The air flow comes out the the four sides of the pink lamp shade and still maintains a consistent air flow. Examples of uses is tents,shed, and etc.You will be protecting your nose from a siege of allergens and bad odors in a crowded tent while you try to go to sleep.
Tan lamp shade rectangular
Pink lamp shade circular
8"x8"x1" merv filter 8 pleated
16# felt pads
2# Rubber o rings
Electrical motor and fan blade from o2 cool
Artist palette plastic
mini rocker switch
6# c batteries and the battery holder
Philips head screw driver
I took the motor and fan blade from the o2 cool simply because shipping seemed expensive ans long since of Christmas season.
No the wires weren't already like that from o2 fan you have to solder the wires on the motor
Take the old tan lamp shade and place the the motor in it and it should be a tight fit but don't glue it yet
i put on some electrical tape hoping that motor wouldn't slide out
i simply put on a two rubber o ring on bottom
and put on the old fan blade on the motor
And at the larger end simply pressed the merv filter and taped it with metallic tape making sure that no air could escape.
then put on the carbon filter measure it out and make sure it is a little bit smaller than the merv filter
Then tape it as long as the tape seals it excellently it doesn't matter what is used although obviously avoid hazardous
Then put 4 felt pads on top of each other at each corner.
make sure it isn't off balance
Then double check and seal off it once more with tape
simply cut a hanger with tin snips bend the opposite it other way of the hook and put it through middle hole of the battery holder
Although yo want to get the the batter holder really close to the top
put on the circular shade on the tan lamp shade and then attach the pack as shown in the picture although i did put some electrical tape at the top of the battery holder
make sure the battery holder doesn't show
keep the wires nice and easy to take off
one wire hooks up to just the battery holder while the other fan blade to the mini rocker switch and another wire mini rocker switch to battery holder . Turn it on and experiment till the air is being sucked in from the bottom
the trace the circle on to the plastic artist palette and spare the hole
cut the circle i used tin snips it was sort of like butter
now tidy up the insulate wires and cut to the length that is nice and short but sticks out one inches above the top of the tan lamp shade.
the poke two insulated wires through the hole in the palette.
then secure each wire to the rocker switch as shown in the picture
add a little slit for the hanger and start taping the plastic palette down
it important that you tape around the rocker switch, tape the hanger and it does necessarily mean that taping the plastic palette needs to be air tight fit.
your finished product varies in size since a 12"x12"x1" filter would require larger lamp shades but its basically still the same formula but a change in materials
mine looks likes like this
This the system I used but to start out put the sensor and the laptop in a container the sensor would measure every 30 sec or so and it would show up on the serial monitor. this was largest clear plastic container I had and I also needed to check in on the laptop since the battery is bad and it mainly relies on the electrical outlet. So it has about 5 to ten minutes or so .
43993 is the lowpulseoccupancy
sensor can detect as low as 1 nanometer in particulate size
sealed in the container i did interrupt it once just a little nervous
lifted the lid and quickly took a picture after enough time had past
here is a close up of data
