Q: "I am interested in purchasing the Roomaid since I understand the unit can be operated both in a motor home or car on a 12VDC power adapter and also on standard AC power. My concern is maintaining the unit. What is involved with that? Do you have any personal experience with the unit? Thanks. Mary
Answer: The Roomaid is made in Canada by Amaircare. I've run a "white" ( it is really cream colored) Roomaid in my home office continuously (except for when I wash the prefilters) for over 9 years. I've changed the HEPA once and the pre-filter maybe 4 times. By the way, I have allergies and have run an Amaircare 3000
continuously in our bedroom for 9 years as well. Original motors still purr along quietly. (German motors.)
Both units are especially needed since Buddy the Siamese cat joined the family a year ago. Since Buddy likes to sleep in his cat bed right next to my monitor, the Roomaid prefilter
does pick up a lot of cat hair over the course of a month (don't believe everything you read about Siamese shedding very little). The annual filter kit includes both pre and post filters
There is also an optional VOC carbon filter
if you are sensitive to formaldehyde or other volatile organic compounds.
To maintain the unit, turn the unit off and wash the prefilters in soapy water, rinse thoroughly and allow to dry. Remember that HEPA filters can become a source of mold or bacterial growth if air does not move through them nearly continuously. Never have an air purifier with a HEPA filter sit idle for more than 3 or 4 days or you need to replace the HEPA.
To change the snap on HEPA replacement filter
you just jank a bit (or maybe use a knife for leverage) and pull off the entire top of the unit which is the HEPA. There are 4 or 5 little peg inserts that snap into the bottom of the Roomaid where the motor is. Then push the new unit on and put on the new prefilter. The post filter sits in the middle of the HEPA unit.
You could add a scent to the top of the HEPA unit. There is a little round container for scent. I choose not to since I am allergic to begin with.
For use in the car, there is a seat belt clip included with the optional 12volt power adapter.
In my opinion, there is not a sturdier unit available in this price range. And certainly maintenance is simple as well.
Thanks for your question.
