Warranty and returns, line by line
| Blue Alpine | Stay Fresh (US) | |
|---|---|---|
| Year 1 | Full warranty on the freeze dryer and vacuum pump for 12 months from ship date (continental US). The owner performs most repairs with Blue Alpine’s instructions and parts | Full warranty, pump included. Stay Fresh repairs or replaces defective parts (AK/HI/PR pay shipping) |
| Years 2–3 | Limited 3-year warranty (36 months from ship date). The FAQ describes 3 years on the refrigeration system | Refrigeration system (compressor, condenser, evaporator) covered under a limited warranty |
| Owner obligations | Clean the condenser every 6 months. If the machine is shipped to the factory and the issue proves to be user error, the owner pays $800 for return shipping | Install, use and maintain per the manual |
| Returns | Within 30 days of ship date: full refund less shipping and a 15% restocking fee. Before shipment: refund less a 3% card fee | 60-day returns advertised |
Read both policies in full before you buy. The biggest practical difference is that Blue Alpine’s first year expects the owner to do most repairs with remote guidance.
Setup notes from the manuals
- Stay Fresh says to wait 24 hours after installation before the first batch, and its manual includes a roughly two-hour vacuum test procedure for diagnosing leaks.
- Blue Alpine asks for at least 6 in of clearance on each side, a medium-sized room to prevent overheating, and space next to the machine for the pump. It lists noise at 65–75 dB, “comparable to a washing machine.”
