Question: How large an area does the Ionic Pro CA200 purify?
Document: This cleaning method let me continue to use the Ionic Pro CA200 rightafter. So far so good, I'm very pleased with this product.
No more and no less, the Ionic Pro CA200 has performed as advertised so far. I have been running it non stop for over a month now and it is still silent!
I got the Ionic Pro CA200 Air Purifier for my daughter's room, becauseregardless of how well I cleaned that room, she always woke up sneezing.
I have owned Ionic Pro for years and needed another one for a bedroom. Air is purified with no filters to purchase or to change out. This brand is reliable, works great, is easy to care for at a reasonable price and lasts for years !Ionic Pro CA200 ionic Air Purifier
Again, the results are not instantaneous as this unit is extremely low flow even for the small confined interior of a car.Note: This is the updated version of the Ionic Pro CA200-B which had problems automatically shutting off for no reason, and had the indicator light blinking for no reason. So far, after a month of use there have been no problems, but I will report back if they arise.
We have a bigger model of this Ionic Pro and if works really well. I needed one for the upstairs as well but didn't want to spend the money on a full sized one. This little guy works just fine for the upstairs area. The car adapter will be nice for allergy season.
I would give this one more stars if it covered a larger area but then again I did buy this knowing how large an area it would cover... so it is up to you.
Now that it is spring, I can open windows to air out the room, which works much better.I moved the Ionic Pro to the basement, which was just refinished (it's a pretty small area). I think that it helps with the smell of new paint and carpet, but I'm really not sure.In my office, I had a small Filtrete air purifier, which marries an ionizer with a HEPA filter.
Courtesy of Amazon Vine, I have received an Ionic Pro CA200 Ionic Air Purifier for review. Inside the box is the unit itself as long as a Car Ionizer that plugs into a car's 12V socket (used to be where the cigarette lighter is.) I have extensive experience with HEPA air filters, and I use a Rabbit Air in both my home and my office. These air filters have worked extremely well over the years even though there is a fan (moving part) in them.
I got the Ionic Pro Compact about 2 weeks ago. I have a triple room which is the living, dining, and kitchen areas all together. When I got the ionizer, I put curtains up to close off this 3 room area from other parts of the house. I then put the purifier on my dining table which is somewhat the center of this space. The instructions said to place it at least 12 inches from a wall is why I decided on this spot.
Answer: Small to medium size rooms.  I'd say 12X12-15X15.  We have this one and it's larger brother in our great room and it is about 20X20, plus an attached dining room. I had it in my office before that...11X11 and it did fine.
