DayStar lets you UPGRADE your filter later!

DayStar knows our owners will have dozens of years of life from their filters.  But what if you want a better filter later? Just Upgrade it!  

DayStar is always happy to upgrade your T-scanner to a Quantum - or upgrade your 0.7Å to a 0.5Å. Our upgrade policy is simple:  For the exact price difference shown on our current product page between what you have and what you want, DayStar will happily upgrade your equipment.

Upgrades require similar time to repair services. Standard payment terms apply. We will thoroughly clean and check your filter while it is in to be sure it is performing to its highest capacity.
