We are aware that although filtering technology has come a long way, as with all technology – it isn’t perfect. However, there is no need to be frustrated ! Our goal is to be able to service all who need in a timely and professional manner. We are constantly working to improve our customer support and need your patience and persistence to improve.

We have numerous support options but first take a look at our troubleshooting tips – they will go a very long way in resolving most of the issues.


In general, all support requests should be through your filter provider as they are best equipped to resolve any issue. If for whatever reason the problem is not resolved then contact us directly.

Support options:

  1. Contact Gentech, USA Nativ, or Netspark directly.
  2. Call – (718) 717-8241 Sunday-Thursday from 4:00 AM -12:00 AM 

If the other options aren’t working, our office has limited support capabilities but we do our best. We will do our best to resolve your issues within 48 hours.
