How does delivery work?
How does delivery work?
Free freight to the lower 48. Your order ships on a strapped pallet by insured LTL freight from the manufacturer's California warehouse.
When it ships. Orders are processed within 2 to 5 business days depending on the brand, and delivery to most addresses in the contiguous US takes 5 to 14 business days after shipment. Transit times are carrier estimates, not guarantees.
How you will know. You get a tracking number by email as soon as your order leaves the warehouse. Most carriers then call 24 to 48 hours ahead to lock in a four hour window, and some send an email or text the morning of delivery instead. Respond promptly either way, because missed attempts trigger terminal storage fees.
How it arrives. A 53 foot semi truck arrives at your curbside and the driver delivers the pallet to the curb. Liftgate service is not included as standard, and standard delivery does not include bringing the equipment inside, up stairs, or unpacking. Someone must be present to sign.
If it arrives damaged. Walk around the pallet and check every box before signing the Bill of Lading. Cosmetic damage can be accepted, but if a carton is punctured or crushed, refuse that item and call us on (888) 500-5675 while the driver is still there. Note the damage on the Bill of Lading, photograph it, and contact us within 48 hours. Once the damage is documented on the Bill of Lading we can file a valid freight claim and ship a replacement at no cost to you. Signing a clean Bill of Lading releases the carrier, and claims filed after one are routinely denied. If you refuse for a reason other than damage, or without contacting us first, return freight costs may become your responsibility.
Where it ships. Free freight covers standard residential curbside delivery within the contiguous 48 states. Hawaii, Alaska and Canada are not available at standard checkout, so contact us before ordering for a freight quote.
What does the warranty cover?
What does the warranty cover?
How long. Cold plunge tubs carry a 1-year limited warranty, when bought from an authorized dealer in undamaged original packaging.
What is covered. Defects in materials and workmanship. The polycarbonate insert, the wooden shell and trim and all other components each carry 1 year, and chillers carry a 1-year manufacturer warranty. Insulated covers carry 1 year, neoprene hose covers 90 days, and replacement filters are consumables with no warranty.
Labor. Any labor cost associated with a claim is not covered. Coverage applies to the original purchaser and is not transferable.
What you have to do. Keep the water balanced and do not let it freeze. Corrosion from poor water maintenance and freeze damage are the two most common reasons a claim is declined. Keep your proof of purchase.
What is not covered. Fading or discoloration from UV exposure, damage from storage in below-freezing temperatures, and corrosion or discoloration caused by lack of water maintenance.
What if I need to return it?
What if I need to return it?
30 days from delivery. The item must come back new, unused and in its original packaging with all components, hardware and accessories. Anything assembled, used or modified cannot be returned, and electronic components such as power supplies and control panels are non returnable under manufacturer policy regardless of condition.
What a return costs. The manufacturer may charge a 20 percent restocking fee, and you are responsible for the return freight. The original shipping cost is not deducted from your refund. Any storage or carrier routing fees incurred during the return are the buyer's responsibility.
Damaged on arrival. A different process, and you are fully protected. If you accepted the delivery and documented the damage on the Bill of Lading, we handle the freight claim and ship a replacement at no cost, with no restocking fee and no return shipping.
Cancelling before it ships. No fee as long as we have not yet submitted your order to the manufacturer. After we submit it but before it ships, an administrative fee of up to 5 percent may apply, and we waive it whenever we are not charged.
To start a return. Email your order number to sales@recoveryroomdirect.com and we issue a Return Merchandise Authorization number within one business day. Write it clearly on every box, because the warehouse will not accept returns without it. Refunds are issued within 5 business days of inspection.
Which brands. Applies to all Golden Designs Inc. brands: Dynamic Saunas, Maxxus Saunas and Dynamic Cold Therapy.
PRODUCT DESCRIPTION
Why Regular Filter Replacement Matters
Your DCT chiller uses a two-stage filtration system: a mechanical cartridge filter (this product) catches particulate matter, while a separate ozonator handles microbial control. The cartridge filter does the heavy lifting — trapping dirt, silt, sand, and suspended particles before they reach the pump and heat exchanger.
A clogged filter restricts water flow below the chiller's minimum threshold (16 L/min), which forces the pump to work harder, reduces cooling efficiency, and eventually triggers the chiller's flow-rate alert. Replacing filters on schedule — every 2–4 weeks depending on use — keeps flow optimal, water clear, and your chiller running at full performance.
Why 20 micron specifically? At 20 microns, these filters capture particles visible to the eye while maintaining strong flow rates through the cartridge. Going finer (5 or 1 micron) would restrict flow and require more frequent replacement; going coarser (50 micron) would allow visible particles to pass. 20 microns is the manufacturer-specified rating for the DCT system.
Key Features
20-Micron Particulate Filtration
Captures dirt, silt, sand, and suspended particles that cloud water and damage pump components.
4 Cartridges Per Pack
A 2–4 month supply for regular users. Stock up to stay ahead of your replacement schedule without repeated reorders.
Quick-Change Design
Standard cartridge format — slides out of the filter housing and replaces in under a minute. No tools required.

Compatibility — Important
These 5" × 2.5" filters are sized for the DCT 0.6 HP chiller only. The 0.8 HP and 1.0 HP chillers use the larger 10" × 2.5" filter housing.
If you have a 0.8 HP or 1.0 HP chiller, you need the 10" × 2.5" filter (DCT-Filter-10x2.5) — available separately on our site.
When to Replace
- Every 2–4 weeks for regular home use (3–5 sessions/week)
- Every 1–2 weeks in high-use or commercial environments
- When flow rate drops below 16 L/min — chiller may alert you or sound louder than normal
- When filter cartridge appears visibly discolored or clogged
Frequently Asked Questions
How do I know when to replace the filter?
Replace the filter when: (1) the cartridge appears visibly brown or clogged, (2) your water flow looks reduced or the chiller sounds louder than usual, or (3) DCT's flow rate alert triggers (below 16 L/min). As a baseline, plan for replacement every 2–4 weeks under normal home use.
Does this filter replace the ozonator or sanitizer?
No. The cartridge filter is a mechanical particulate filter — it removes suspended solids but does not address bacteria, algae, or dissolved contaminants. Your DCT chiller's ozonator handles microbial control separately. Both systems need to be maintained for clean, safe water.
Can I rinse and reuse these filters?
We do not recommend it. Rinsing may dislodge captured particles back into the cartridge rather than removing them. DCT's filter cartridges are designed as single-use replaceable items. Reusing clogged filters risks restricted flow and reduced filtration efficiency.
What happens if I use the wrong filter size?
The 5" cartridge will not seat properly in the 0.8 HP or 1.0 HP filter housing — the housing is designed for a 10" cartridge. Using the wrong size creates a gap that allows unfiltered water to bypass the cartridge entirely. Always match the filter size to your chiller's HP rating.
