How to Store Your BOROUX Filters
If you're not going to use your BOROUX foundation filters for a while, follow these storage tips to preserve their integrity. Whether you stock up on extra sets of filters and don’t use them immediately or are away from home for a while, proper storage can ensure the carbon filters last for years.
1. Keep it Simple
If you’re only going to be gone for a weekend, or even a long weekend, there’s no need to do anything special! Your BOROUX filters are fine to sit where they are. The filters are incredibly dense, so it’s highly unlikely they’ll dry out in that short time. If, for some reason, you notice slower flow upon your return, try priming the filters again.
2. Use the Fridge
If you’ll be gone for 7-10 days, consider storing your filters in the fridge. Keeping the filters in the fridge maintains a humid environment. Remove the filters from the canister and place them in a water-retaining container, like a zip-top bag. Keep the filters moist so that you don’t have to prime them upon your return. Just make sure the filters don’t freeze, as freezing can permanently damage the internal structure and their filtration ability. BOROUX filters can stay in the fridge for up to 30 days. When you return, reassemble, refill your upper chamber, and enjoy!
3. Dry Out the Filters
If you won’t be using your BOROUX filters for an extended period, dry them out. Drying the filters ensures mold doesn’t occur. It usually takes 3-5 days to fully dry out; we recommend laying the filters on a towel to dry. You can leave the filters on the counter, or once they’re completely dry, put them back in their original packaging or a similar cardboard box.
4. Keep Odors Away
Carbon can hold onto odors like a disgruntled aunt can hold onto grudges—a long time. Be mindful of where you store your filters to ensure they don’t pick up unpleasant smells. For example, storing filters in a garage may cause them to pick up petroleum odors, so the next time you use them, they may smell like a gas station.
5. Treat Your House-Sitter to Filtered Water
Hire a ‘BOROUX babysitter’ to come over and run water through your system every couple of days. Have them empty the lower chamber (bonus: use that water for your plants or pets) and refill the upper chamber. This keeps the filters wet and activated. There’s no need to re-prime when you return because it’ll be like you never left.
6. Mind the Temperature
Wherever you store the filters, keep the temperature between 35 and 85 degrees. Just make sure they don’t freeze or overheat.
BOROUX filters are truly incredible because they can last for so long! The filters can be wet, dried out, stored for years, and then used again. The number of times they can be completely dried out and re-primed is indefinite.
