Use of air purifier for dust mite allergy?

[Jerry_NJ]

I am now considering taking measures to reduce the amount of dust mite exposure with some focus in my bedroom.  First, careful vacuuming with a HEPA equipped tools and adding mite proof covers to my bed pillows.  Now, to the subject, I have moved my forced air furnace delivery system to using a MERV 11 air filter.  The next step to remove mites from the air could be addition of an air purifier in the bedroom.  This would be again make use of filtration that is fine enough to catch mites, something like 0.3 microns.  

Does anyone have experience with using these measures, particularly the air purifier (electric fan driven filter)?

Thanks,

Sorry when I "jumped" in on this thread I though I was on a thread I have on the "dog" community..that's why there is a bunch of stuff about dogs.  Please, my intent was to share info with dog owners, not imply any connection between humans and my dog... other than I think treatment of my dog's condition may help me fight a night time nasal congestion. If that happens I'll report that result here totally in the human context.

The only other allergens for Wilson is Bay Berry... which we do not have on our property.  There were several versions of Dust Mites to which his blood tested showed an allergy, some very high.  On a scale used anything under 10 indicated no treatment indicated... then the scale when up in several steps stopping with over 100 (must be the threshold of "over the top").  Wilson had some over 200 in the mite category.

Still I have decided to address the source rather than the symptom.  Ongoing careful dust control with HEPA vacuum and damp cloth dusting, new dog beds and steps to address human beds.  Being winter lower temperatures and humidty are easy to achieve and I have taken to putting some soft items outside to freeze than to shake and dust before bringing back into the house.  I have ordered an air purifier and have a high MERV 13 rated filter on the forced air furnace (geo heat pump, runs a lot, in fact I have the circulatory fan on 100%).  I have also ordered some mit killing spray "safe for human and pets" and will be careful in its use, such as the mattress on next washing of the sheets.

The vet agreed my attempt to remove the cause rather than treat the symptom is worth a try.  We can go to allergy shots if my "better house keeping" doesn't improve Wilson's condition.

Wilson is still on some treatment from Ketaconazole and antibiotic,  until the supply runs out.  His ears no longer need treatment twice a day.

He is still being feed a restricted proteine diet and based on some inputs I will try to remove potato from his diet - guess that means rice, a grain, one type of food I have been avoiding.   He loves ground kibble with carrot, lettus, cooked black beans and the like.  The kibble is still the prescription Hills z/d which has a hydrolyzed chicken protein. It goes for agout $5 a pound, happily Wilson is a small dog and with the veggies added he eats less than a cup of kibble a day.  The vet said to get him to eat some dry kibble to help clean his teeth.

I got some sizes wrong, dust mites are over 100 microns in size and good HEPA filters stop particles as small as 0.3 microns, so a HEPA filter in a vacuum and air purifier, and furnace should remove airborne dust mites.  Living mites get trapped in the filter and die, and the particulate mater form the mites, bodies and waste also gets trapped.
