Best Air Purifier To Remove Dust Particles?
i currently have a honeywell 18155 i dont know my rooms exact measurements its an average bedroom i figure its between 500-700 sq feet well the honeywell doesnt seem to be doing the job ive had it since febuary of this year,my room has alot of dust and i know i have to dust but it should make some what of a difference and it hasnt when i clean the hepa filter and replace the pre filter theres dust in there but still i see tons of air born particles in the air…so im looking for a new purifier for my sized room that will do a much better job then this and that either doesnt need filter replacement or doesnt need it often and if it needs replacement every few months it cant be to expensive price of the purifier should be no more then 400 would love to spend less then that but really need something thats going to do the job this one truely i dont see a difference in my allergies or anything else in the air

When picking an air cleaner, you have to keep in mind the total volume of air in your room, not the square footage. That is because we live in 3 dimensions, not 2. Take the length x width x height of ceiling to get the volume. When shopping for a machine, read the box or literature to find the CFM of air moved by the machine (this is the cubic feet of air per minute moved by the motor). Take your volume and divide it by the CFM to determine how many minutes it will take to get one air exchange. You want about 8 exchanges or more per hour (6 minimum!). Also, look for machines that are not made out of plastic, because that off-gases chemicals back into the air, you also don’t want a filter that is glued together. The Filtrete filters the other person mentioned are not HEPA filters. They are for the AC or furnace and are available in MERV ratings from about 8 to 12. Those filters are more about keeping your A/C and furnace equipment and ducts cleanand not really about keeping the air in your bedroom clean. I am going to send you a link to an article that talks about all the different kinds of air cleaners and how to comparison shop for them. I personally have a Healthmate in my bedroom and I have had it for about 9 or 10 years. It rocks.
You could look at the filtrete units they carry at target. They look ok and the room size rating is on the box. there are two models, and the filters are about 20.00 each. If you look deeper I know I have seen hepa filters units that only require a washing or vaccuming of the filters. This eliminates the cost of replacement, I know they are out there and the units are not expensive. The old honeywells, I know I have one, are loud, and expensive. Mine sits in a closet. You could also check out Ebay they have tons of air filters. One word of advice stay away from the sharper image garbage and the oreck garbage those charged metal slat filters do not work at all. I have owned them, I have one in my furnace and they do not collect worth a darn. Totally a waste of money.

Vacuum Cleaning Is Ineffective At Removing Dust Mite Allergen, According To Study
Science Daily — New research has shown vacuum cleaning to be largely ineffective at removing dust mite allergen.
Conducted by the Woolcock Institute of Medical Research the research found that vacuum cleaning was an ineffective allergy avoidance measure because it removed dust mite allergen from carpets in an inconsistent and incomplete manner.
This is particularly true of worn carpets where the study results indicate vacuum cleaning may in fact change the distribution of dust mite allergen within the carpet, rather than removing allergen from all depths equally.
Woolcock Researcher Jason Sercombe said that given that carpets are a major reservoir of dust mite allergen and vacuum cleaning is the most common method of allergen control, the results are particularly relevant to professionals interested in limiting people’s exposure to common allergens.
“The results also help to explain why many trials aimed at reducing people’s exposure to indoor allergens – some even going so far as to install new furniture – have had limited success.
“Although soft furnishings such as beds contain more concentrated sources of allergy causing protein produced by house dust mites (known as Der p 1), the large size of carpet means it is likely to contain a larger total amount of allergen than other items in a home,” said Mr Sercombe.
“Allergen avoidance measures that rely solely on vacuum cleaning are likely to be of limited success unless more rigorous cleaning than standard home vacuuming is performed.”
The Woolcock study also showed the type of vacuum cleaners with rotating brushes in the head removed more dirt and allergen from the carpets than those without. However, rotating brushes may serve to kick dust up into the air if the suction component of the cleaner is not operating properly.
For the first time, the study demonstrated that carpets after several years of use in domestic conditions not only contain large amounts of Der p 1 allergen but that this allergen occurs throughout the depth of carpets with no consistent pattern.
The Woolcock Institute conducted the study in an attempt to better understand how allergen avoidance measures can be applied to carpets. It examined the vertical distribution of the allergy-causing protein produced by house dust mites present in several used carpets before and after a standardised vacuuming procedure using either of two styles of dry vacuum cleaner.
“Overseas studies have found that vacuum cleaners with two or three layer bags performed better than those with a single layer bag, and the maintenance of the cleaner and integrity of seals and gaskets were important factors in effective cleaning,” Mr Sercombe said.
“There are many vacuum cleaners on the market that claim to be suited to allergy sufferers. The most important aspect to look for is HEPA (high efficiency particulate air filter) filtration which is finding its way into some very affordable models.”
Dust mite allergen exposure can be reduced by:
·Washing bedding items weekly in hot water (55 degrees C or more, special anti-mite additives provide little additional benefit over hot water with normal detergent)
·Avoiding non-washable items such as sheepskins
·Regularly washing pillows and doonas and/or purchasing mite-resistant covers
·Washing any stuffed toys
