Introduction: Battery Operated Air Purifier

Picture of Battery Operated Air Purifier

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.

I took the motor and fan blade from the o2 cool simply because shipping seemed expensive ans long since of Christmas season.

Step 2:

Picture of

No the wires weren't already like that from o2 fan you have to solder the wires on the motor

Step 3:

Picture of

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

Step 4:

Picture of

i put on some electrical tape hoping that motor wouldn't slide out

Step 5:

Picture of

i simply put on a two rubber o ring on bottom

Step 6:

and put on the old fan blade on the motor

Step 7:

And at the larger end simply pressed the merv filter and taped it with metallic tape making sure that no air could escape.

Step 8:

Picture of

then put on the carbon filter measure it out and make sure it is a little bit smaller than the merv filter

Step 9:

Picture of

Then tape it as long as the tape seals it excellently it doesn't matter what is used although obviously avoid hazardous

Step 10:

Picture of

Then put 4 felt pads on top of each other at each corner.

Step 11:

Picture of

make sure it isn't off balance

Step 12:

Picture of

Then double check and seal off it once more with tape

Step 13:

Picture of

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

Step 14:

Picture of

Although yo want to get the the batter holder really close to the top

Step 15:

Picture of

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

Step 16:

Picture of

make sure the battery holder doesn't show

Step 17:

Picture of

keep the wires nice and easy to take off

Step 18:

Picture of

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

Step 19:

Picture of

the trace the circle on to the plastic artist palette and spare the hole

Step 20:

Picture of

cut the circle i used tin snips it was sort of like butter

Step 21:

Picture of

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.

Step 22:

Picture of

the poke two insulated wires through the hole in the palette.

Step 23:

Picture of

then secure each wire to the rocker switch as shown in the picture

Step 24:

Picture of

add a little slit for the hanger and start taping the plastic palette down

Step 25:

Picture of

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.

Step 26:

Picture of

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

Step 27:

Picture of

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 .

43993,0.15,76.8

43993 is the lowpulseoccupancy

0.15 ratio

76.8 concentration

sensor can detect as low as 1 nanometer in particulate size
