Purifier: The humidifier can actually make the issue worse. It is good to use one if the humidity is too low, below 30% can dry the nasal passages and lungs.

I run cool mist humidifier and air purifier at night but I wake up every morning with a headache. Do you have any ideas why? Thank you

As an allergist,: I cringe a little when I hear about humidifiers because they are ripe for biofilms (colonization by bacteria and fungi). If it helps you, please clean it thoroughly and regularly with bleach. Sensitivities to fungus can be a cause of chronic rhinitis and it may be your trigger. Other benign causes of morning headaches include snoring/sleep apnea, migraine, grinding teeth/TMJ pain, poor sleep etc ...Read more

Which one amongst the three can be the most effective tool for severe indoor allergy : 1. Vaccum cleaner 2. De-humidifier 3. Good air purifier?

Which one amongst the three can be the most effective tool for severe indoor allergy :
1. Vaccum cleaner
2. De-humidifier
3. Good air purifier?

Depends: It depends on what allergens you are sensitive to. An Allergist can help figuring that out. As a general rule of thumb: -Vacuum with a HEPA filter: good for dust, animal dander, mold, and other allergens trapped in carpeting (getting rid of it is better)
-De-humidifier: good for molds and dust mites
-HEPA/UV purifier: molds, animal dander, pollen that comes in, and other irritants. ...Read more

Best air purifier for eczema?

Unfortunately none: There has been no study, I am aware of, showing that using air purifier helps eczema. In fact, it may potentially dry up the skin further with increased air movement. Hepa filter appears to be the most effective if you do want to try. Be sure to measure the room size and that the filter will move the total volume of room air about 5 times per hour. ...Read more

Air purifiers: The most effective air cleaners are the hepa filter type and the electrostatic air purifiers. The hepa filer traps most allergens in the filter so that clean air passes through. The electrostatics work by placing an electric charge on all particles coming into the filter and then passing them through metal plates that have an opposite charge so the particles are pulled out onto the plates. ...Read more

How high up in the air should i ideally place my hepa air purifier in my apartment? (I have allergy's)

How high up in the air should i ideally place my hepa air purifier in my apartment? (I have allergy's)

At the nose level?: There is no study I am aware of on this issue. The most part is the amount of air filtered per hour (4-5 exchanges). I would only advise this for the bedroom when patients have pet allergies yet insisting on keeping a pet. Overall, I am not that impressed with HEPA filter although some people do derive benefit from it. You'd be better off consulting an allergist. ...Read more

Will a hepa air purifier do anything for the air quality in the house? Like cut down on amount of dust in the air? Is it worth it to buy one?

Will a hepa air purifier do anything for the air quality in the house? Like cut down on amount of dust in the air? Is it worth it to buy one?

Yes: however, it is impractical to expect the whole house will be purified by a single HEPA Filter. One for each room is expensive but may actually make a difference. Filters at the basement/Heater hvac systems are available but have limited effectiveness.

What is the best in-home air purifier for allergens including mold?

HEPA filter: The best type of filter is one that says "hepa" on it — do not get an ionizer. Ozone is produced by machines that advertise things like "mountain-fresh air" and is irritating to the nose, sinuses and lungs. The various manufacturers make different bells and whistles, but you'll be good if you buy one that says hepa. They are sized based on the size of the room; don't get a bigger one than you need. ...Read more

Covered broken asbestos tile with carpet but no loose pieces, is there still a danger?. I have air purifier with a true hepa filter on all the time.

Covered broken asbestos tile with carpet but no loose pieces, is there still a danger?. I have air purifier with a true hepa filter on all the time.

Unfortunately: Asbestos fibers can permeate carpeting and would still pose a health risk. The risk is not close to that posed to industrial workers or those working with tile (eg sawing), but the long term risk posed to you is unknown since it is a carcinogen and many years will transpire before a malignancy develops. Recommend looking into the cost of removal and limit any carcinogen exposures (eg smoking) ...Read more
