HF0101 / HF0301 Foldable KN95 Particulate Respirators (Without Valve)

Brand: SATA | Product: Foldable KN95 Particulate Respirator (Without Valve) Series | Standard: GB2626-2019 KN95

This series of non-powered air-purifying particulate respirators includes ear-loop and head-strap versions without exhalation valves. They use a 5-layer high-efficiency, low-resistance structure, with adjustable internal nose clips and sponge nose pads for a tight facial seal. Designed for protection against non-oil particulates such as dusts, fumes and mists.

Model Configuration Overview

Model	Wearing Style	Valve	Key Features
HF0101	Ear-loop	No	5-layer structure, high-efficiency low-resistance; adjustable internal nose clip with sponge pad; includes 5 S-hooks per box for neck wear.
HF0301	Head-strap	No	Wide knitted head strap for improved comfort during long-term use; 5-layer structure.

Key Features

5-layer High-efficiency Low-resistance Structure

Both HF0101 and HF0301 use a 5-layer structure, typically including non-woven fabric, electrostatic cotton, melt-blown fabric, etc., providing ≥95% filtration efficiency against non-oil particulates.

Good Fit and Seal

Adjustable internal nose clip combined with a sponge nose pad, together with wide knitted head straps or ear loops, helps achieve a tight facial seal and reduces leakage.

Neck-wear Assistance (HF0101)

HF0101 includes 5 S-hooks per box to convert the respirator into a neck-worn style, enhancing comfort during extended use.

Applications

Grinding and cutting: Operations such as grinding, sawing and sweeping generating dust, fume and mist.
Material handling: Environments with mineral, flour, wood and pollen particulates.
General maintenance: Equipment maintenance and cleaning with dispersed non-oil particulates.
Daily protection: Personal particulate protection in non-high-risk medical environments (not for oxygen-deficient, IDLH or high-concentration toxic gas environments).

Frequently Asked Questions

Q: What is the difference between KN95 respirators and disposable face masks?

A: KN95 respirators comply with GB2626-2019 and provide ≥95% filtration efficiency against non-oil particulates, suitable for industrial dust, fume and mist environments. Disposable face masks (e.g. HF0210) are typically tested to standards such as GB/T 32610 and are designed for daily protection against droplets and general particulates, with different performance levels and intended use scenarios.

Q: What is the difference between KN95 and N95?

A: KN95 refers to the Chinese standard GB 2626-2019, while N95 refers to the U.S. NIOSH standard. Both require ≥95% filtration efficiency against non-oily particulates and are considered equivalent in terms of particle filtration performance.

Q: How long can KN95 respirators be used? When should they be replaced?

A: Continuous use is generally recommended not to exceed 4–8 hours. Replace respirators immediately if they become wet, damaged, breathing resistance increases significantly, or they are contaminated by splashes. In high-dust or high-contamination environments, replace more frequently.

Q: How to choose between head-strap and ear-loop models?

A: Head-strap models (HF0301) are better for long-duration wear, as wide knitted straps reduce ear pressure and are suitable for tasks lasting several hours. Ear-loop models (HF0101) are easier to don and doff and are suitable for short-term, frequent removal; combined with S-hooks, they can be converted to a neck-worn style for improved comfort.

Q: Are these respirators suitable for protection against harmful gases and vapors?

A: No. GB2626-2019 specifically states that it does not apply to respirators for protection against harmful gases and vapors. For protection against gases and vapors, choose gas masks and corresponding filter canisters complying with GB2890.

Q: Can this valveless KN95 be used in medical or epidemic settings?

A: Valveless KN95 respirators offer good particulate protection for the wearer and can be used for personal protection in general medical or epidemic situations. However, in operating rooms and other sterile environments, follow institutional policies.
