Kona Best BBQ Grill Mats
Skip until coating is disclosed; Kona does not specify the non-stick treatment, raising PFAS uncertainty.
Kona Best BBQ Grill Mats are non-stick coated fiberglass cooking mats, but the brand doesn't disclose the coating chemistry or PFAS status.

Material
Woven fiberglass fabric with unspecified non-stick coating
Brand disclosure
Brand is silent on PFAS
Lab data
No public lab test
What’s concerning
Non-stick, chemistry undisclosed
Advertised as non-stick but coating type is not explained.
Category baseline
PFAS exposure happens more often with clothing products.
No PFAS disclosure
The company has not publicly discussed PFAS in this product.
Non-stick coating degradation and Teflon-type coating fume risk
The coating identity is undisclosed; if it contains Teflon-type coating (Teflon), fumes become possible above 400-500 degrees Fahrenheit. Kona's silence on this point means degradation risk cannot be confidently ruled out. Visual damage to the coating increases this risk.
Fiberglass fiber shedding
Woven fiberglass can shed microscopic fibers if the coating wears or if the weave is damaged by metal utensils or high mechanical stress. While fiberglass itself is not classified as a carcinogen in modern epidemiology, inhalation of shed fibers during use is an avoidable exposure.
Heat-related coating integrity loss over time
Repeated thermal cycling (heating and cooling) can cause non-stick coatings to crack, bubble, or separate from the fiberglass substrate. Kona provides no durability or replacement guidance, making long-term safety maintenance unclear.
What’s reassuring
Coating leachables into food
No testing data or recalls suggest the coating leaches into food under normal grilling conditions. However, lack of FDA food-contact certification from Kona means this has not been independently verified for this specific product.
Formaldehyde / VOCs
Industrial fiberglass weaving sometimes uses formaldehyde-containing resins; Kona does not disclose the resin type. At grilling temperatures, off-gassing is unlikely to be significant, but confirmation would require material safety data.

What it's made of and why it matters
Kona Best BBQ Grill Mats are woven fiberglass fabric, a silicate-based weave chosen for heat resistance and non-adhesive properties. The non-stick coating applied to the fibers is not specified by the brand, which is the primary safety gap. Fiberglass itself is stable at high heat; the risk lies entirely in the coating's composition and degradation behavior over repeated grilling cycles.
The brand's record and disclosure
Kona is a private-label cookware and grilling brand sold primarily through online retailers. The company does not publicly disclose coating chemistry, certifications (such as FDA approval for food-contact surfaces), or PFAS status. No product recalls or safety controversies are on record for this specific mat line, but the absence of transparency on non-stick treatment prevents independent verification of safety claims.
How it compares in its category
Grill mats compete on heat tolerance (typically 400-600 degrees Fahrenheit) and non-stick performance. Fiberglass mats are common in this category; competitors include silicone-based mats (less heat-tolerant but often more durable) and stainless steel mesh alternatives (no coating, no PFAS risk, but less non-stick). Kona's fiberglass approach is mid-range, but the unspecified coating puts it at a transparency disadvantage versus brands that disclose Teflon-type coating or ceramic treatments.
If you buy it
Confirm your grill's maximum temperature and verify the mat is rated for that setting (manufacturer claims 400-500 degrees are typical; check the product label). Hand-wash with mild soap and warm water after cooling; avoid metal utensils that can scratch the coating. Replace if coating shows visible peeling, discoloration from food staining that won't clean, or any texture changes. Store dry to prevent mold growth in the weave.
