The hair was stuck on the first prefilter which is washable, so I vaccuumed that. The HEPA filter and activated charcoal/carbon? filter was replaced recently, they last about 2 years when you can feel the air output is not as strong. I've had the pair of air purifiers for about 7 years, replaced the filters every 2 years. It is not magic but considering how much hair and dust the filter picks up, its work it for us.
Also, if you are thinking of using a one of those high MERV pollen type filters on your furnace, careful you don't kill it. (and cracking the hear exchanger, same as a clogged filter, can be deadly)lead wrote: ↑ interesting about the diy
its been mentioned before on other sites on diy air filter. They recommend a filter should be at the front not the rear where it sucks in as recommend by the air expert in cbc video. Now why? Its a fire hazzard if you suck air thru the filter on a sealed diy.
The diy air filter like all filters can run 24/7 and the motor on the fan is rated for its flow of air. Once you inhibit the air flow you will add a strain to the fan motor to work properly. Quick example hold your hand over your vacuum's hose/end and you'll here the engine noise get substantially louder and work harder. When the air flow gets too bad you could potentially cause a short in the fan motor as it will over work from too much resistance and could potentially causing a fire if not monitored.
The recommended method I read was one piece of tape across the top of the box fan that is slightly tillted so it rests by its own weight on the fan so it pushes the air thru at lowest speed. Once the filter is too clogged to blow thru. The filter will push away from the fan and so air flow can escape before it risks undo strain on the motor and you'll also know it needs to be replaced.
This is Sharp's explanation of how Plasmacluster generates ions: https://global.sharp/pci/en/about_pci/JeganV wrote: ↑ I'm glad they're testing these, like any product category you really never know whether the claims they're making are true. I do use 2 Sharp Plasmacutter ones, the main reason for using them in the first place was I have a horrible pollen allergy. Outside or in a car I felt fine but when I go home I'm a total mess of runny nose and sneezing constantly. Plopped one of these things and I no longer had these problems at the house anymore, so not a placebo effect for me, although perhaps the house's air system was horrible though. I now moved over to a condo, at this point all these things do is lessen the dust, so I wouldn't mind a really powerful one being used temporarily. I'm curious how much it costs to have that inspector the CBC hired, since we have zero way of knowing some of those things.
Would definitely like them to do another episode specifically on the ion generator or plasma air cleaner part. Are there any that produce no ozone and if they do, how much? Hope not of course.
I didn't mean the whole house, I placed them where I was very likely to be, bedroom being the primary one, the other one moved if I was going to stay in a room longer than usual. I was the only one who needed it.
Did you notice any difference between whether they were supposedly ionizing or not? Just curious.
Genuinely I can't tell about that part. All I could tell it was doing was filtering the pollen supposedly what ionizers are tasked with doing. However, I couldn't tell if it was the ions really making this better for me or whether it was just the plain good HEPA filter that really did the work. I didn't really take the chance, as on a bad pollen allergy day I could dispose of a whole tissue box.
Shouldn't you change that filter more often??
