FAQs

How does the membership billing work?

There's no upfront cost - your first system is free. You'll only be charged $25.47 every 6 months when your replacement bulbs ship. There are no annual fees or hidden costs. Each billing is clearly communicated before shipping.

What makes Guardian Club different from just buying the bulb?

With a Guardian Club membership, you don't have to worry about checking and ordering replacement bulbs for your unit. Once your Guardian Club membership is activated, the bulbs will be auto-delivered to your doorstep every 10 months. The best part is that you only have to pay when your bulbs are shipped.

What maintenance does the system require?

Besides making sure that the installation is done right and the connections are secure, the only thing needed is bulb replacements. The unit's bulbs last for approx. 8,000 hours (~333 days) and will need changing periodically for continued usage.

What exactly is included in my Guardian Club membership?

With the BioShieldUV Guardian Club membership, you avail a 15% discount on your replacement bulbs and get free lifetime unit warranty.
