Berkshire CH809.10, Choice 800 Knitted Wiper, 9in x 9in, Case of 1,500
Berkshire CH809.10, Choice 800 Knitted Wiper, 9" x 9", Case of 1,500
The Berkshire Choice 800 is a 100% polyester knitted cleanroom wiper designed for ISO Class 4 environments and compatible with ISO Class 5 through ISO Class 8 applications. Built from continuous-filament polyester with a knife-cut edge, the Choice 800 offers reliable low-lint performance for a broad range of cleanroom wiping tasks — from general surface maintenance to equipment cleaning in electronics, pharmaceutical, and medical device manufacturing environments. The knife-cut edge provides a clean, consistent perimeter without the added cost of ultrasonic sealing, making the Choice 800 a practical option for facilities that need polyester wiper performance at a more accessible price point than the Choice 700.
MTE Solutions stocks the CH809.10 in cases of 1,500 sheets (150 wipes per pack, 10 packs per case). The 9" x 9" format is the standard size for cleanroom bench operations, and the Choice 800’s all-polyester construction makes it compatible with IPA, acetone, and most common cleanroom solvents. If your process requires a knitted polyester wiper for ISO Class 4–8 work and you’re looking for a cost-effective alternative to sealed-edge wipers, the CH809.10 is a strong candidate.

Frequently Asked Questions
What is the difference between the Choice 800 and the Choice 700?
The primary difference is the edge treatment and ISO classification. The Choice 700 (CH709.14) features an ultrasonically sealed edge and is laundered in an ISO Class 4 cleanroom, making it rated for ISO Class 3–5. The Choice 800 uses a knife-cut edge and is rated for ISO Class 4–8 — a broader range at a more accessible price point. If your environment is ISO Class 4 or lower classification, the Choice 800 is a cost-effective alternative.
What does “knife cut” edge mean?
A knife-cut edge is produced by cutting the wiper to size with a blade rather than ultrasonically sealing the perimeter. It produces a clean edge suitable for ISO Class 4–8 environments, though it generates slightly more edge fiber than an ultrasonically sealed wiper. For ISO Class 3–5 applications, a sealed-edge wiper like the Choice 700 is recommended.
What ISO cleanroom class is the Choice 800 rated for?
The Choice 800 is rated for ISO Class 4 through ISO Class 8 environments (equivalent to Federal Standard 209E Class 10 through Class 100,000).
How many wipes come in a case of CH809.10?
Each case contains 1,500 wipes — 150 wipes per pack, 10 packs per case.
Can the Choice 800 be used with IPA or other solvents?
Yes. 100% polyester knitted wipers are highly compatible with isopropyl alcohol (IPA), acetone, and most common cleanroom solvents.
Is the Choice 800 laundered before shipping?
The CH809.10 is a knitted polyester wiper but does not carry the same ISO Class 4 laundering specification as the Choice 700. For applications requiring pre-laundered wipers, see the Berkshire Choice 700 (CH709.14).
