Neotec XJ-2000 Review

I bought two Neotec XJ-2000 unlts a few years ago upon recommendation from a coworker.  I had been waking up each morning congested.  I overheard my coworkers discussing various ionic air purifiers one day, saying they really helped with nasal congestion, and allergies. One had bought a large whole house unit (another brand) for $500 and was saying it made the wall behind the unit black and the replacement filters needed to be changed often and were quite expensive.  Another said he bought a Neotec unit and liked it and it had a washable filter and no black wall.    Upon his recommendation, I checked out information online and also bought.  According to the website, the two units would cover my living and bedroom area sizes. The units shipped promply.   I did like the smell of the air, and it did seem to help my congestion. I let them run all the time.

I cleaned the metal pull out filter at least once a month per the instructions that came with the unit. It was not too bad to remove, wash and re-install.  Then I noticed after 8 months, the units both started emitting blue sparks and I could hear it making sparking noises.  I re-read the instructions and it said to remove the whole shell cover and clean the inside thoroughly, every 6 months or when the airflow becomes weak, but there were no instruction provided on how to do this. There were no screws visible to "remove the shell".  I emailed the company for instructions to remove the shell and thoroughly clean them,  but got no response and my coworker who had recommended the unit had moved on.

 I used the units only very little since, and only in my (awake) presence as I am afraid of the sparking.  Also i have since read some reports of ionic air not being good for your health, so i may give up on these units. 

To be fair this was an older model and they say they have a new design now. My unit  says it was made in China.
