This year I added more to my website and stirred up a lot of controversy. I came up with the answers to a lot of my questions. The biggest was finding a new airpurifier that was 100% sealed. The 2nd biggest thing I uncovered was the carbon issue. Why are so many people complaining about the same air purifiers I sell that I rated good. They bought models that were sold from stores that the activated carbon totally went bunk. I now go though the manufacture and stopped dealing with places that discount their purifers much cheaper than the ones I ge from the manufacturer. I knew there was somehting strange when people are complaining about them and every one I sell I rarely get complaints. Most bought on auction websites and stores that stock them. Activated carbon, for example, has a shelf life.
I stopped selling ozone machines. I was big on Aranizer. I dont' carry that one or any ozone machine for that matter. I go to extremes to avoid ozone creation. Some of the UV bulbs in Hepa purifiers even produce ozone. Not the ones I promote.
Go to my ozone page to read my reviews.
Pressure sensors were also more popular this year. More people now on't want the timers that monitor the fan speed and hours the purifier was on. Its hard for the purifier to tell if the place was dirty or clean. It just goes by time. Most of the timer ones by the time it said to change it was not as clogge as the ones that had sensors.
Note: The filtering levels of the Hepa filters even when clogged actually gets better, not the opposite. Also, the trapped polutants will not leach back out into the room, even if its a cheap hepa filter. Its mostly a matter of having good seals so it doesnt leak.
Most hepas last about 5 years anyway.
A good hepa filter lasts about 5 years no matter what someone tells you. they told me that the cheeper ones last 2 years and theirs 5 years. Funny thing is that I ask them if they ever owned one. They say that they have heard stories but never owned one for 5 years. THEN DON'T MAKE CLAIMS IF YOU DON'T KNOW THEY ARE 100% TRUE AND JUST REITERATE INFO YOU HEAR.
More people watn more air excahnges per hour. The more expensive the purifier, the more they usually exchange per hour. The better ones will do the same high exhanges per hour but with lower noise and little to no vibration in the purifier.
Beware of older bunk carbon filters that have lost its positive harge. Activated carbon is positively charged on factory fresh filters. The gases and odors in the air are negativly charged. Every year the active carbon loses its positive charge. This is why when I see a new air purifier sold too cheap too be true, I always know something is off. I can look up the cereal number on the box but every time I ask the people especially on auction websites they never respond to my email. No wonder they don't have a phone number on their auction. I have also emailed dealers on Amazon and I never get a response when I ask for the cereal number. They probably think I'm trying to find out if the air purifer was stolen. Who knows.
An older filter can have just 10% of its active positive charge left. The first thing Ido when I get a new carbon filter is to test the charge of it to see if how positive it is. Some companies add potasium and zeolite to their carbon to change it also.
Expensive air purifier - Least expenisve - Most expensive - THE CHEAPEST AIR PURIFIER TO RUN
Only way to test is to get a Kill-O-Watt meter from Radio shack and test it for myself. I know that the DC motors use less electricity but are more expensive motors up front. Expecially the Brushless DC types. AC brushed types are different.
The new motors this comapny has in their purifiers is DC, not AC. It uses no where near the average 200 watts of power that most require. This is beyond any rating out there. Most have an Energy Star rating that rate the wattage it uses. This brand makes even the most efficient ones look expensive to run. SEE MY ORANSI PURIFIER REVIEW
AC MOTOR VS DC MOTORS
Most air purifiers unless stated on the manual have AC motors. DC is much more expensive and usually cost over 1000 for the air purifier. The DC motors cost more up front but can cost as much as 90% off the power bill. The cheapy machines have the same power as the more epxnesive ones but cost more to run. So, if a air purifier claims 500 CFU and is 700 bucks and other one is 1500 bucks. The 1500 dollar one usually has the DC motor. The most expensive motors are the motors that just came out are the ones that convert the AC to DC energy. Coverters already built in. These really do save 90% of the cost of running it. On high, instead of paying 1.30 a day, it costs 13 cents a day to run it.
The most effecient motor I have tested is the Oransi motor. Its a German motor that is pretty new to the market. See this type of motor on this page here.
