When you need to store your Berkey water filters for an extended period of time, such as when going on vacation, there are some important steps to take in order to preserve the filters and prevent damage. Proper storage will help keep the filters in optimal condition until you return and are ready to use them again.
Why Is Proper Storage Important for Berkey Filters?
Berkey filters utilize carbon and other media to remove contaminants through adsorption and absorption. Exposing the filters to air, moisture, freezing temperatures, or other environmental factors for prolonged periods can impact filter performance and lifespan. Additionally, biological contaminants may build up on the filters if they are left damp or wet. Storing the filters correctly protects the sensitive media and prevents premature degradation.
Moisture Exposure
Allowing Berkey filters to dry out completely will damage their ability to adsorb contaminants. However, leaving them damp for weeks or months promotes bacterial and mold growth. This can clog pores in the carbon and render the filters ineffective. Finding the right balance of moisture is key for storage.
Freezing Temperatures
Extreme cold can cause the filter media to expand and contract. This stresses and tears the porous structure, reducing performance. Freezing temperatures should always be avoided when storing filters long-term.
Dust and Dirt
Berkey filters are designed to adsorb microscopic particulates. However, allowing excessive dust or dirt to build up on the filters while in storage can lead to clogging and reduced contaminant removal capability.
Chemical Exposure
The activated carbon and ion exchange resin in Berkey filters are vulnerable to chemical degradation. Gasoline, solvents, and other chemicals can interfere with proper adsorption if filters are exposed during storage. Keeping them isolated from these contaminants preserves efficacy.
Prep Steps Before Storing Berkey Filters
Taking a few preparatory steps before storage will help keep Berkey filters in better condition for when you need them again:
- Flush the filters per manufacturer instructions to rinse out any accumulated particulates or contaminants.
- Allow filters to air dry completely before storage to prevent moisture issues.
- Seal filters in airtight packaging like plastic bags to prevent dirt or dust buildup.
- Note the date of storage to keep track of when filters need replacement.
Ideal Storage Locations
Where you store your Berkey filters is just as important as how you prep and package them. The best storage locations will be:
- Inside – Temperature and humidity controlled indoor spaces are less likely to damage filters.
- Dry – Avoid damp basements, sheds, garages or other humid areas.
- Clean – Select storage areas free of chemical fumes, dirt and dust.
- Accessible – Choose spots that are easy to access when you return from travels.
Closets
Closets inside your home provide ideal storage conditions in most cases. Filters will be protected from moisture, freezing, chemicals and other hazards. Hang filters towards the back of the closet to prevent accidental bumps or disturbances.
High Shelves
Kitchen, laundry, or utility room shelving units make suitable storage spots as long as they are high enough to keep filters clean. Make sure no dangerous household chemicals are kept in the same vicinity.
Storage Totes
Clear plastic totes with sealing lids make excellent filter storage containers. Look for brands made of thick plastic that won’t easily crack or warp. The clear construction allows you to inspect filters without opening the lid.
Do Not Store In:
- Attics – prone to extreme temperature fluctuations
- Basements – often damp and humid environments
- Garages – may contain gasoline or chemicals
- Sheds/Barns – dirt and dust could damage filters
Recommended Storage Time
Berkey filters can typically be stored for up to 5-6 months before performance begins degrading. Storing for longer than this risks damaging the filter media and shortening useful lifespan. Always check the manufacturer’s recommendations for your specific filter models.
Short Trips
For vacations or trips lasting 1-2 weeks, filters can simply be left in place in the Berkey system. For added protection, run a full tank of purified water before leaving so there is no standing water in the lower chamber.
Month Long Journeys
Traveling for 3-8 weeks requires filters be removed and stored to prevent biological growth. Follow the proper storage steps to maintain filter integrity and performance for this duration.
Seasonal Storage
Storing Berkey filters for several months at a time when a second home sits vacant or during long international trips is possible. Inspect filters prior to reinstallation to ensure no damage has occurred.
Year Round Storage
Allowing filters to sit in storage for longer than 6 months risks permanent damage to the media. Either replace them upon return or store in short duration increments.
Proper Packaging Techniques
To protect Berkey filters during storage, pay close attention to how you package and seal them. This will provide an impermeable barrier against moisture, dirt, and other hazards.
Plastic Food Storage Bags
Thick food grade plastic bags are an affordable storage option. Look for bags designed for freezer use as these are more durable. Seal the bags completely removing any air pockets.
Vacuum Sealing Bags
For the best protection, utilize a vacuum sealing appliance to remove air and create an impermeable seal around filters. This prevents moisture damage during storage.
Plastic Containers
Storage containers made of durable plastic and with airtight sealing lids make excellent filter storage vessels. Ensure gaskets are intact to prevent air exchange or moisture entry.
Aluminum Foil
Wrapping filters tightly in aluminum foil can provide an additional layer of protection and reflect radiant heat. Use heavy duty foil and wrap completely with no gaps or tears.
Oxygen Absorbers
Placing an oxygen absorber packet inside storage containers or bags will prevent filter media oxidation while stored. This preserves efficacy and lifespan.
What to Avoid When Storing Filters
Just as important as proper storage techniques are things that should always be avoided when storing Berkey filters:
- Do not store damp or wet – Always dry completely before packaging
- Never freeze filters – Keep stored above 32°F (0°C)
- Avoid direct sunlight – UV rays accelerate degradation
- Do not stack or crush – Damage to media will occur
- Never store near chemicals – Fumes can penetrate packaging
Recharging Filters After Storage
Once returned from travel, your Berkey filters may need recharging to refresh performance. This involves flushing fresh water through the filters before use. Check manufacturer guidelines for recharging details.
Flush with Purified Water
Fill upper chamber with clean water. Run at least 1-2 full upper/lower cycles. This rinses away any loose contaminants or dust.
Backwash Filters
Reverse flush filters one at a time from bottom up into a container. Repeat 2-3 times each filter to dislodge any particulates.
Activate Carbon
Mix up 1 cup water with 1 teaspoon household bleach. Fill filters and let soak 15 minutes. Rinse thoroughly. This oxidizes and reactivates carbon sites.
Check Flow Rates
Time and record flow rate through each filter. Compared to old data, this validates they were not damaged in storage.
Consider Replacements
If flow rates are slow or filters show visual damage, replacement may be needed sooner than expected.
FAQs
How do I maintain moisture in stored filters?
After drying filters, place a damp paper towel in storage bags/containers to provide some moisture without allowing the filters to get wet.
What temperature should I avoid when storing?
Do not allow filters to freeze or be exposed to temperatures above 100°F as this can damage filter media. Ideal storage temp is 60-80°F.
Can I reuse packaging materials each time?
Reuse plastic bags or containers but replace oxygen absorbers each storage cycle. Wrapping filters in new aluminum foil each time is recommended.
How do I prevent mold growth?
Ensuring filters are completely dry before packaging, using oxygen absorbers, vacuum sealing, and avoiding humid storage areas prevents mold.
Do I need to label stored filters?
Yes, label with the date of storage, filter type, and any notes. This allows you to monitor time in storage and replace if needed.
Conclusion
Properly storing Berkey water filters when away for extended trips or vacations is important to maintain filter integrity and performance. Take time to completely dry, individually package, and stow filters in stable indoor spaces free of contaminant exposure. Limit storage duration to the manufacturer recommended window. Upon return,refresh filters by flushing and reactivating the media. With some care and preparation, you can keep Berkey filters ready for use when home again.
