Hepa Filter Efficiency





hepa filter efficiency






    filter efficiency
  • method of expressing a filter's ability to trap and retain contaminants of a given size.

  • The efficiency of various filters can be established on the basis of entrapped particles; i.e., collection efficiency; or on the basis of particles passed through the filter; i.e., penetration efficiency.

  • The operating results from a filter as measured by various criteria such as percentage reduction in suspended matter, total solids, biochemical oxygen demand, bacteria, color.





    hepa
  • A high efficiency particulate air , or HEPA , filter is a type of high-efficiency air filter.

  • HEPA stands for High Efficiency Particle Arrestor, used to reduce the number of contaminants in indoor air. A HEPA filter will arrest or stop 99.97% of all particles .3 microns or larger.

  • short for High Efficiency Particulate Air – often used to refer to the level of filtration for vacuum cleaners or dust extraction.

Well seeing how I already did my 365 photo earlier today... at like 1am... I figured I might take some time to relax and do nothing at home. Though of course I still felt like going out shooting. It rainined A LOT earlier today, and I was hoping for a thunderstorm but that never came around sadly. I actually wanted to do a shot outside in an open field during the thunderstorm that was suppose to happen today.

I took this shot at some stream at the side of the road, I was actually looking for a pond or something but turns out google maps is a little outdated because the small pond I was heading for is gone now and has been replaced with a warehouse. So I found this while driving around that area. I walked down towards the stream, planted my tripod in the water and put my camera on, I used a 10 stop ND filter along with a 2 stop graduated ND filter. After taking a few shots I put away the graduated ND filter in my bag and turned back to my camera and lord and behold there was some large thing right in front of my camera. It was moving around and I had no idea what it was so I was a little freaked out and stood up, when that happened it came up a little to dive back down, turns out it was a beaver... When it dived down it smacked its tail on the water splashing me and my camera hahaha. Never seen on that close before hahaha. To bad I didn't take a shot of it but I had my 10 stop ND filter still on my camera so that wouldn't have turned out well.

Not a lot I can say about this image other than it caught my eye when I was loading my bags in to the car. It was then off to a mobile phone supplier meeting. The notable bit was in the salvage area where the host grabbed a iPhone 4 and proceeded to smash it into the corner of the workbench and not happy with this, he dropped it on the floor and stamped on it for good measure. Other than a few scratches, it was fine ........ Chris beware! LOL!

So, meeting done, I wanted to grab some shots while there was still light ...... On a recommendation, I was at a carpark and unable to pay the ?2.50 to stay. I was about to turn around, when the attendant said I could park anyway. I have agreed to pay ?10 to a local hospice in return for his kindness.

After more messing around, I found myself at the Roaches and decided I'd watch sunset from on the top, as I knew of a small pond I could work with. Bloody hell! It was windy, cold and the sunset never happened but I hope to have some shots, as the light disappeared completely.

So, back to the Abbey Inn and guess what ........ I couldn't get in my room! Proper keys but wouldn't go in. I wondered if Darrel intended me to take the middle room, so tried there - the key fitted and in I went ..... laptop case ...... shoes ....... Ahhh, guess I shouldn't be here!

Back to the pub, food and proper keys ...... G'night!
