Air Flow

I have slept better for 2 nights now - it is the purified air that makes the difference.

The HEPA helmet is too heavy for the CPAP machine - the CPAP machine is made in 3 sections, and it started to come apart last night. So that experiment is over.

I have 2 floor mounted HEPA room air purifiers that I have used consistently since the surgery. I bought them last year, but stopped using them because I wasn't notcing much difference.

My mind was clearer today when I woke up. My apartment has 1 1/2 baths - my bedroom has the 1/2. It's just a sink and a mirror. I saw something new in the mirror today. The mirror always seemed to be covered with dust. Yet the main batroom only got hard water spots. I saw a pattern in the dust today - in the streaks on the mirror. The dust is coming from the A/C vent.

Then I put it altogether. The venting comes in a straight line over the front door, and goes straight back to end with the vent into my bedroom. All the other vents come off of that duct shaft with shafts at right angles. So most of the air flow would come into my room. My filing cabinet sits 5 feet from that vent - a straight shot. The filling cabinet is black. It is always covered in tons of dust. But this was the only place in the house that had that much problem. There is dust in the rest of the house - but a very light film that takes a long time to build up.

So - I retrofitted one of my HEPA purifiers and placed the intake directly in front of the A/C vent - mounted 7 feet over the floor. The results have been very good.

I did a slow vacuuming of my room yesterday. There is only 125 square feet of rug available to vacuum in my bedroom. The rest is under a bed and my computer chair floor mat. That small amount of rug, when vacuumed slowly, completely filled the vacuum canister with fiber and dust (30 minutes of time - max). I am going to keep doing that each day until the vacuum picks up very litttle.

I got some things done today, lots more than any other day in the last few months, but got tired pretty easily. Took 2 naps in between.

I put a new HEPA filter in the unit, plus a new carbon pre-filter. The HEPA filter needs to be changed yearly, and the carbon pre-filter every 1 to 3 months. I will be changing the pre-filter every month from now on. It is always coated with grey dust. I compared the used HEPA filter with the new one. The used one had only been used in frequently over the last year - and continuously for at least a month now. The used filter had a huge off white stain on it. I may have to change it more than just yearly.
