Replacement Dehydrator Trays Worth Buying Again
Excalibur’s replacement polyscreen trays top this list for buyers running an Excalibur dehydrator, since they match the original mesh spacing exactly. Nesco’s Clean-A-Screen trays follow for that brand’s stackable machines, and Comfecto’s universal silicone sheets suit anyone needing a size-flexible fix.
Excalibur’s replacement polyscreen trays are the safest first stop for anyone whose original tray cracked, since they are made to the brand’s own tray dimensions and mesh spacing.
We compared machine-specific fit, mesh material, and owner reports on warping under heat to rank these seven tray options, since most buyers are replacing a part rather than shopping blind.
Our top picks
Excalibur Dehydrator Polyscreen Trays
These polyscreen trays match the mesh spacing of Excalibur’s original inserts, so food that previously fell through gaps on a worn tray sits properly again. They fit directly into Excalibur’s square tray frames without modification.
Pros
- Mesh spacing matches Excalibur’s original trays exactly
- Fits directly into existing frames without trimming
- Lighter than the solid tray frames they replace
Cons
- Only fits Excalibur’s own tray frame dimensions
- Thin mesh can sag slightly under very wet foods
Nesco Clean-A-Screen Dehydrator Trays
Nesco’s Clean-A-Screen trays snap into the brand’s round stackable tray system, adding a fine mesh surface for small items like herbs that would otherwise fall through the base tray slots.
Pros
- Snaps directly into Nesco’s existing round tray slots
- Fine mesh holds small items like herbs and sliced garlic
- Stackable design matches the machine’s expansion trays
Cons
- Round shape only fits Nesco-style stackable machines
- Plastic mesh is less heat-rated than metal alternatives
COSORI Dehydrator Mesh Screen Trays
COSORI sells these mesh screens sized specifically for its own Premium dehydrator line, aimed at fruit leather and small-item drying where the stock tray spacing is too wide. They slide into the existing tray frames.
Pros
- Sized to slide directly into COSORI’s own tray frames
- Silicone coating resists sticking from fruit purees
- Mesh gauge is tight enough for small sliced items
Cons
- Only fits COSORI’s specific tray dimensions
- Not sold as a universal fit for other brands
Tribest Sedona Dehydrator Trays
Tribest’s Sedona line uses interchangeable stainless mesh trays alongside solid trays for liquids, and these replacement mesh inserts match that dual-tray system. They fit the brand’s own tray frame dimensions.
Pros
- Stainless mesh outlasts plastic alternatives under heat
- Matches the brand’s dual mesh and solid tray system
- Rigid frame resists warping over repeated use
Cons
- Premium pricing compared to plastic mesh competitors
- Only fits Tribest Sedona’s specific frame size
Magic Mill Dehydrator Trays
Magic Mill sells direct replacement trays sized for its own dehydrator models, useful when an original tray cracks or warps after years of use. The mesh spacing matches the stock trays shipped with the machine.
Pros
- Matches the stock mesh spacing on Magic Mill machines
- Direct fit without needing to trim or modify
- Lower cost than buying a full new dehydrator
Cons
- Plastic mesh can discolor with highly pigmented foods like beets
- Only fits Magic Mill’s own frame dimensions
Bear Dehydrator Mesh Trays
Bear’s mesh trays are sized for its own compact dehydrator models, with a mesh gauge tight enough for small sliced items like dried herbs or thin fruit chips. They slide into the machine’s existing tray guides.
Pros
- Fine mesh suits small sliced items without fallthrough
- Slides directly into existing tray guides
- Lower price point than metal mesh alternatives
Cons
- Only fits Bear’s compact dehydrator frame size
- Plastic construction is less durable than stainless mesh
Comfecto Universal Silicone Dehydrator Sheets
Rather than matching one brand’s exact frame, Comfecto sells flexible silicone sheets that can be trimmed to fit most round dehydrator trays. They work as a reusable liner over an existing mesh or solid tray.
Pros
- Trims to fit most round dehydrator tray sizes
- Reusable silicone replaces disposable parchment liners
- Works as an added liner over existing mesh trays
Cons
- Needs trimming to match your specific machine’s size
- Not a structural tray replacement, only a liner
What to look for
Why dehydrator trays wear out before the machine does Trays see direct heat and repeated flexing every time food is loaded and unloaded, which is more wear than the heating element or fan experience. A cracked frame or torn mesh usually shows up well before the motor fails, making tray replacement the more common fix.
Matching a replacement tray to your exact machine Dehydrator tray frames are not interchangeable across brands, since tray dimensions, mesh spacing, and mounting slots differ. Buyers should match the replacement to their dehydrator’s brand and model line first, before comparing mesh gauge or material.
Mesh gauge for small items versus thicker cuts A finer mesh keeps small items like herbs, thin fruit chips, or minced garlic from falling through, while a coarser mesh dries faster with better airflow for thicker slices like jerky or apple rings. Some brands sell both gauges for the same machine.
When a universal liner beats a brand-specific tray If the original tray frame is still intact and only the mesh surface has failed, a trimmable silicone sheet can patch the problem without ordering a brand-specific part. A universal liner is not a fix for a cracked or warped frame itself.

Good to know
Are dehydrator trays interchangeable between brands?
No, tray dimensions and mounting points differ by brand and model, so replacements need to match your specific machine.
How often do dehydrator trays need replacing?
Plastic mesh trays often need replacing after a few years of regular use, while stainless mesh can last much longer.
Can you use parchment paper instead of a mesh tray?
Parchment works for some foods but blocks airflow from below, which slows drying compared to open mesh.
What mesh size is best for drying herbs?
A fine mesh gauge keeps small herb leaves from falling through while still allowing airflow around them.
Are silicone dehydrator sheets reusable?
Yes, silicone sheets wash and reuse many times, unlike disposable parchment liners.
Why did my dehydrator tray crack?
Repeated heat cycles combined with flexing during loading and unloading are the most common causes of cracked plastic trays.
Can I trim a universal tray liner to fit my machine?
Most silicone universal sheets are designed to be trimmed down to match your dehydrator’s tray size.
Do stainless mesh trays dry food differently than plastic mesh?
Both allow similar airflow; stainless mesh simply holds up longer under repeated heat exposure than plastic.
Is it cheaper to replace trays or buy a new dehydrator?
Replacement trays are almost always cheaper than a new machine, especially for mid-range and premium dehydrator models.
The verdict
Excalibur’s replacement polyscreen trays are the right pick for anyone running an Excalibur machine, since the mesh spacing matches the original exactly. Nesco and COSORI owners should go with their respective brand-matched trays instead, and anyone whose frame is intact but mesh has failed can patch it with Comfecto’s trimmable silicone sheets.
