Any experiences with new air cleaners? > Any experiences with new air cleaners? email me for PDF Indoor Air 2005; 15: 420-431 Comprehensive quantitative experiments were performed to assess the capabilities of several air-cleaning devices to create a particle-free microenvironment as a therapy for sleeping persons affected by allergic rhinitis and asthma. Six devices were evaluated, of which five were portable and intended to provide general air cleaning for bedroom-sized spaces. The sixth was intended for installation in front of the headboard of a bed and was designed to provide clean air focused in a space occupied by a sleeping person. The air- cleaning methods of the selected devices included high-efficiency particulate air (HEPA) filtering and electrostatic precipitation. Particle concentration measurements for six particle-size ranges and sound intensity measurements were made during 8-h, sleep-simulating periods. The effects of four parameters were studied: (i) device location, (ii) controlled air motion in the laboratory, (iii) airflow rate setting of the air-cleaning device, and (iv) controlled disturbances. To ensure a totally objective study, a special laboratory facility was constructed which enabled complete control of the experimental conditions. The measured concentration histories provided comprehensive evidence of the relative capabilities of the various devices for the specific air-cleaning function. It was found that the device designed to focus the cleaned air in the sleeping space fulfilled its goal and, in that regard, was clearly superior to all of the other air-cleaning devices. the trick is being able to get thru the tons of different air cleaners and then get the best economic and effective machines. My theory is most consumer machines are worthless at least past a week. So the goal becomes gettting the best air filter at the lowest price that can be replaced every month or every few weeks. >> Any experiences with new air cleaners? > email me for PDF [quoted text clipped - 37 lines] > that regard, was clearly superior to all of the other air-cleaning > devices. > the trick is being able to get thru the tons of different air cleaners and > then get the best economic and effective machines.

Effective filters such as HEPA rated are absurdly expensive to replace. I tossed out my room filter because replacements were $65 and as you pointed out last a month or two at best (rated to last 1 year). >> the trick is being able to get thru the tons of different air cleaners and >> then get the best economic and effective machines.

Yes most definitely, that piece of information is not widely touted. These things might last for five months but its not effective past a month or two at most. Man, the peoplewith asthma have all sorts of good surprises to look forward to. I really meant to address that exact problem. I think they should make lower expensive hepa filters and machines that would utilize them . Right now I have modified a cheap air cleaning machine, which is basically a machine that intakes air and exports treated air back into a room after it passes thru a limited flow of space. I was at first excited at the prospect of using filtrete filters instead till I realized they are cheaper and less effective versions of hepa filters. So I bought a mid size air cleaner and searched for the lowest cost hepa filter that would still be effective I can buy to put into it. The one I buy now costs around 22 dollars and its not tiny . I have to jam it into the machine that really didn't even come with this size hepa filter.So make a long story short, if you modify a machine with the cheapests best hepa filter you can find, its like the best I can do. Every three weeks I toss it or every month and so instead of tossing the outrageously expensive larger ones from Sears that cost 90 bucks not including tax, or using it past its intended effectivness, I just buy the 22.00 model ten times a year . the only problem is it covers a lot less space then the giant ones. What are you going to do though? Personally I wish I could get all asthma couples together to afford a home in like Albuquerque or Colorado with allot of clean air. Of course if anybody is interested, they can write me mscantpollution@yahoo.com > I wish I > could get all asthma couples together to afford a home in like > Albuquerque or Colorado with allot of clean air. Denver has one of the highest levels of pollution in the country. Other cities in Colorado are nice but there are few jobs. Albuquerque has decent air but again, the job market isn't great. $65 per month is not that bad after all. Say, if that filter really worked, would you mind giving $65 away every month to feel well? I personally spend about $500 a month on my search for cure. The problem is that these filters indeed can reduce the particulate contamination by as much as factor of 10, but no health benefits have been demonstrated. Filters still may work for some individuals who don't fit in the average population: their imporvment may get averaged out during statistical calculations. E.g. I find that exercising outdoors in a HEPA mask makes a MAJOR difference. Asthma is a very multi-dimentional disease, and it take a lot experimenting to understand your particular case. > $65 per month is not that bad after all.

Where do find this or buy this I just heard on radio while I was doing something that air stream that is pointed directed on the person who needs is, does get some form of relief. 200 a month is not allot to pay for better health if you can afford it. If I could afford 500 a month I would have made a beeline out of this concentration camp they call life here in PHIlly and Pa. > but no benefits have been demonstrated? How is that determined? Google Scholar >> but no benefits have been demonstrated? How is that determined? > > Google Scholar I don''t disbelieve but I want to hang on with some hope. There is a tiny improvement. Right now we are getting freezing weather but clean air or relatively clean air and I am lucky to have no symptoms but there is going to be a day when even that won't help , for now I tried to show how particulate pollution is the only cause of my illness and disability. i told people I would work for an apt or whatever it took to get to clean air. Nada... I don't know what to do. I tried to show other negative links to this kind of air (moderate or worse particulate pollution in my city) and there are many but what can I do, the newsmedia ignores it. |
