Medical Forum / Diseases and Disorders / Asthma / August 2005Hepa Filtration
I have a Honeywell DA 5010E , which I assume is the European equivalent of the 50100. Apart from having trouble getting filter spares in either Ireland or the UK (although I have found a few places in the US), has anyone any recommedations for a replacement model or experience of using a plain HEPA system (I'm staying away from the ionising ones). Suggestions of suppliers would be a help as well.

I have a wonderful catalog sent to me in the mail for asthma products and have seen the Hepa filtrations or as we call it here filters. If you would like I would be glad to search for you.

Michelle Thanks. I'd be interested in recommedations of ones that other people are using. The Honeywell I've got is great, but difficult to get hold of in the UK/IRL anymore. I was looking at the AustinAir, BlueAir and others. Would you mind telling me the supplier/catalog you have?

To summarize: It is a well known and much lamented fact that those people who most *want* to rule people are, ipso facto, those least suited to do it.

To summarize the summary of the summary: people are a problem." -- Douglas Adams ------------------------------------------------------------------ Let me get back to you after I look at the catalogs. Michelle I have a honeywell ( big one) and recently went to Honeywell website and after sending them a photo they were able to find a filter . They are not really good at providing all the filters they have on their website, which makes me wonder at the end of day how committed they are with their products. That said, I have no idea how it works. all I know that in high pollution days I need my asthma meds.Consumer reports and others here have suggested to clean their filters every so often with vacuum cleaners , or at least the prefilters. The bottom line is I am still looking for something that will clean the air in home especially of particulates that usually is associated with breathing problems. I am much less concerned with pollen and dust mites? Why? Cause I see a larger correlation between the quality of air outside then I do inside. On good air days I have much less problems . Its too bad most Americans don't get this information and then they would know how poisoned some of us are in Ne states and they would be able to correlate the connections. Some reason our press and newsmedia does not care, they worry about Michael Jackson instead. Getting back to which is more effective? I am still trying to get to that question. Hamiliton Beach has a UV portable air system that utilizes a uv lamp to do something.I read the lamp is not powerful enough to do much. Anyone know more about this. I have not followed this group in a while. I am up to share an apt in clean air state if your sober and have good attitude. :) > I have a Honeywell DA 5010E , which I assume is the European equivalent of > the 50100.

They have a charcoal filter which you don't change and then a prefilter which is where all the yuk goes. Its easy to clean. You just hold it under a stream of water until its clean, let it dry a little then put it back in. We've had these units about 9 years now and have never had to buy any replacements for them. They have several settings. Some may not like the noise. Being in the center of town, I don't mind the noise since its white noise and helps block the outside noises when I sleep. I believe we paid close to $500 per unit. I don't know what they go for now though.

G'day Rae, I see you mention charcoal filters but that they are quite old. Has anyone mentioned to you that these filters saturate and can become quite useless. Some have a regeneration process but that would depend on the items. Cheers, Merlin. I don't think the charcoal really does anything. Not sure what if anything, it does. But the filters are still working great. When I don't change them in a while, I can really see the dust and stuff that they've collected. They may be outdated, but they work for me. They have a "super clean" setting, the noisy one, and then the low and high setting and a fan only setting. I thought the hepa filters had to be changed out. I didn't know they had ones that could be cleaned. Maybe it was just the old ones that were that way. I had heard the filters alone for those were around $200.

G'day Rae, yes the basic larger particle filtering is usually done by the paper elements or whatever but the carbon or charcoal granules perform a different kind of filtering by absorbtion of gaseous types of material, more or less by molecular absorbtion into the actual charcoal complex. But these materials can become saturated and do need replacement from time to time, dependent on their application and the actual atmosphere where they are being used. They may appear to be in pristine condition. I believe there was a rejuvenation process using heat but it would probably be easier just to buy new elements. Of course if you are experiencing no problems it is probably best to leave the thing alone. I experimented with negative ionisers for a couple of years and found they were also very useful as particulate collectors, many airconditioning systems have these devices operating in them, especially large shopping type complexes. I do believe one organisation has pushed the operating envelope a bit far and generated quite a bit of "flak" and bad information with regard to "ozone" happening but basically the principle and operation of a properly designed ioniser is incredibly sound. The transmitter heads do degrade which does require regular maintenance. TV's and appliances generate significantly more ozone, laser photo copiers are probably the greatest problem.. Cheers, Merlin. I've been using a Vornado hepa filter these five or six years. (Under $200) I'm on my second principal filter ($49) Not the quietist but I'm able to use it at the lower of five settings, number two. Or three when the principal gets old after two years or so . Yes the prefilters can be vacuumed or washed in dish detergent. Every month or three according to need. Because of heat, cold, pollution and humidity my little New York apartment is sealed off from the world outside maybe two hundred days a year. De humidifier, two air-conditioners, an oxygen concentrator (prescription) and the Vornado. Big electric bills! Optimum air.---Jack jack Whast an oxygen concentrator? Of course I can look it up :) too. > I've been using a Vornado hepa filter these five or six years.

UV is usually advertissed to kill germs, not to remove pollen or pollution. Sounds pretty useless to me, especially if it generates ozone.

Another big whoopy-do as far as asthma sufferers are concerned although perhaps a benefit if you live with a smoker. >I thought the hepa filters had to be changed out. They do. The *pre*filters can be cleaned. The HEPAs are too dense and fine for vacuuming or washing. SignatureAlison Chaiken "From:" address above is valid. (650) 236-2231 [daytime] http://www.wsrcc.com/alison/ Mr. Wilson [ . . . ] and even his wife's outing have as much to do with the real story here as Janet Leigh's theft of office cash has to do with the mayhem that ensues at the Bates Motel in "Psycho." -- Frank Rich, NY Times, July 17 I bought one of these UV units from Radio Shack just to check out from Radio Shack. it did nothing and probably made my asthma worse cause they give off a little ozone I think After two weeks another waste of money and actually made my asthma worse. Of course no days of good quality air adds to my nightmare of a life. > > Hamiliton Beach has a UV portable air system that utilizes a uv lamp > > to do something.I read the lamp is not powerful enough to do [quoted text clipped - 15 lines] > They do.
