I’m not a huge fan of calling 720-numbers to buy accessories & replacement parts for various products & purchases.
I had an office chair a decade ago that I enjoyed very much, but the arm rests were notorious for cracking where 1 of the bolts was situated.
I went through four of those arm rests before throwing the chair away for good. Every single time I wanted a new arm rest, I had to flip the chair & situated the special 720-number near the serial number & other warranty information. Despite the fact that the arm rests were free & covered by the device’s warranty, it would have been much easier to have access to these parts on a website or cellphone app. I ran into the same exact issue with these UV air purifiers that I got multiple months ago. I am trying to keep our indoor air as clean & free of harmful contaminants as much as I possibly can. They’re fancy machines that do what they advertise, but they have disposable HEPA filters that need to be replaced after five to multiple months of constant use. I had a feeling that the manufacturer would either sell them at the store where I obtained the UV air purifiers, or would at least have a store on their website with parts and pieces. Sadly however, I was forced to call another unusual 720-number just to get new filters for our UV air purifiers. I was linked to a call center overseas, but they pulled up our model & had the part ordered in minutes. It arrived at our cabin later that month. In the end, it wasn’t as taxing of a process as I initially expected & I am simply glad to have clean UV air purifiers once again.
