How Much Is a Freeze Dryer? What It Costs to Buy, and to Run

A home freeze dryer costs between $2,699 and $5,355 new, and running one costs roughly $6.70 in electricity per full 15 lb batch plus about $230 a year in oil, bags, oxygen absorbers and filters if you run a batch most weeks. Over five years that works out to around $5,600 all in for the Standard with the Premier pump — which means the price tag you see on the product page is a little under half of what you will actually spend.

That second number is the one almost nobody publishes. Harvest Right and Blue Alpine both have pages on electricity cost. Neither itemizes oil, bags, absorbers, filters and the parts that wear out, which is where the rest of the money goes. So here is the whole thing, with every figure taken from our own published specifications and current catalog prices rather than estimated.

What the machine itself costs

Stay Fresh builds three chamber sizes. The Standard takes either a 5-tray or a 7-tray insert and either of two pumps, which is why it shows up at four prices.

Shipping is free from our California facility. Military, first responders and teachers get 10% off, which takes the Standard to $2,429. There is also a 12-month, no-fee layaway plan — the Standard works out to $224.91 a month with no interest and no financing charge, which is a different thing from a 0% promotional APR that reverts.

Things people budget for that are already included

Every machine ships with a 12-inch impulse sealer ($54.99 on its own), 50 mylar bags ($29.99), 50 packs of oxygen absorbers, a pack of silicone mesh, an oil filter, trays, and a 168-page recipe book. If you are comparing us against a machine where the sealer and bags are a separate line item, add about $100 to theirs before you compare.

Electricity: about $6.70 a full batch

A full 15 lb batch in a Stay Fresh Standard with the Premier pump uses about 37 kWh over roughly 45 hours. The freezing phase is cheap — only the compressor runs, at about 400 W. Drying is where the money goes: the compressor keeps running, the vacuum pump starts (about 300 W for the Premier, 400 W for the Commercial), and the 650 W shelf heaters cycle on about a third of the time, for an average of about 850 W with the Premier pump and 950 W with the Commercial. A lighter batch costs less: our phase-by-phase electricity breakdown measured an 8 lb batch at about 18.5 kWh over 24 hours.

The EIA forecasts a US average residential rate of 18.2 cents per kWh for 2026. At that rate, with full 15 lb batches:

Scale it to your own bill. Washington State averages about 13.6 cents, while California and Massachusetts run past 30, so the same full batch costs about $5.00 in Washington and over $11 in Massachusetts. Running overnight on a time-of-use plan is the only lever that moves this number much.

Pump oil, and the comparison that surprised us

Oil-sealed rotary vane pumps need their oil changed, because water vapour ends up in it. This is the one running cost that differs sharply between the two pumps we sell, and it is worth understanding before you choose.

Both pumps move the same 7.2 CFM, so neither one dries food faster. The Commercial pump pulls a deeper ultimate vacuum — 3.75 micron against 15 — and six times fewer oil changes is a real quality-of-life difference when you are running back-to-back batches.

Here is the part we would rather tell you than have you work out later. Upgrading from the Premier to the Commercial pump at checkout costs $661. The oil saving is about $37 a year at one batch a week — but the Commercial pump draws about 100 W more while it runs, and at the US average rate that costs about the same again in electricity. So on running costs the upgrade never pays for itself, however often you run it. Buy the Commercial pump because you want a quieter pump you can repair instead of replace, or because you are selling what you make and cannot afford downtime. Do not buy it expecting the oil savings to cover it, because they will not.

One genuine piece of arithmetic in the other direction: adding the Commercial pump at checkout costs $661, while buying that same pump separately afterwards costs $1,295. If you think you will want it eventually, wanting it now is $634 cheaper.

Bags, absorbers and the rest of the consumables

This is the category people underestimate, because each item is small and you buy it constantly.

• Mylar bags — a 50-pack of 8" x 12" bags is $29.99. A 15 lb fresh batch typically fills three or four of them. At a batch a week that is about four packs a year, so roughly $120.
• Oxygen absorbers — we ship 50 packs with the machine and then, honestly, we do not sell replacements. Budget $15–20 per hundred elsewhere. It is the one recurring consumable we will send you off-site for.
• Parchment paper — $15 for 100 sheets in Standard size, $25 in Mega. Optional, but it makes candy and anything sticky far easier to get off the tray.
• Fresh air filter — $9, replace annually.
• Pump demister — the Premier demister is $70. On the Commercial pump the replaceable element is $95 and the whole assembly is $245, though you are replacing the element, not the assembly.
• Extra trays — not a consumable, but worth mentioning: a second set of four is $95. Having two sets means loading the next batch while the first is still bagging.

Parts, five years out

Freeze dryers are refrigeration machines with a vacuum system bolted on, and refrigeration machines eventually need parts. We publish the prices because a machine you can repair for $50 is worth more than one you replace for $2,699.

A door gasket is $50 and is the part most owners replace first, usually somewhere past year three. An acrylic door is $120 if you scratch yours badly enough to care. A relay is $10, a solid state relay $25, a touch screen $120, a compressor $250. The first year carries a full warranty and the refrigeration system is covered through year three, so most of this sits outside a realistic five-year budget — the total below allows $100, which is probably generous.

The five-year total

Assume a Standard with the Premier pump, 50 batches a year, 15 lb of fresh food per batch, and the national average electricity rate.

That is 3,750 lb of fresh food processed, so roughly $1.50 per pound of fresh food in, machine included. Specify the Commercial pump instead and the total goes to about $6,300, or $1.68 a pound — the cheaper oil does not offset the higher purchase price, and the pump’s extra electricity uses up the oil saving anyway.

Whether $1.50 a pound is good depends entirely on what you put in. Garden surplus and clearance meat make it look excellent. Freeze-drying candy you bought at full retail makes it look like an expensive hobby, which it is, and an enjoyable one.

What about the cheaper machines?

Harvest Right has been discounting hard: its Home Pro bundle was listed at $1,895 against a $2,495 regular price, and a Medium starter kit at $2,395. That is genuinely less money than our Standard. What the extra buys here is a larger chamber at the same footprint, a KF25 vacuum flange so hoses and gauges are stocked parts, a motorized ball valve that closes the vacuum line whenever the pump stops, a standalone vacuum valve, and a food probe — plus lifelong free technical support and a 60-day return window. Our side-by-side comparison lays out all of it, including where we come out behind.

The other thing you will see is a $65 "freeze dryer" on a marketplace listing. Those are not freeze dryers. There is no vacuum pump in them, which means no sublimation, which means they are dehydrators with optimistic marketing. We went through the whole price ladder in what every price band actually gets you.

When not to buy one

If you will run fewer than about ten batches a year, the machine never earns its keep — the fixed cost dominates and a chest freezer does more for your money. If you have no 15–20 A circuit you can dedicate to it, factor in an electrician before you order. And if you are buying specifically to sell what you make, read the state-by-state rules on selling freeze-dried food first; in several states the machine is the easy part and the licensing is not.

If you are still choosing between sizes, our 2026 buyer's guide works through that decision, and the vacuum pump guide goes deeper on the four specs that actually separate one pump from another.
