HF0204V Foldable KN95 Particulate Respirator (With Valve)

Brand: SATA | Product: Foldable KN95 Particulate Respirator (With Valve, 4-Layer) | Standard: GB2626-2019 KN95

HF0204V is a non-powered air-purifying particulate respirator (KN95 foldable, with valve), featuring a 4-layer high-efficiency, low-resistance structure and an exhalation valve for improved comfort. It uses a head-strap design with adjustable internal nose clip and sponge nose pad for a tight facial seal.

Key Features

4-Layer High-efficiency Low-resistance Structure

HF0204V uses a 4-layer structure including non-woven fabric, electrostatic cotton, and melt-blown fabric, providing ≥95% filtration efficiency against non-oil particulates.

Exhalation Valve Design

The exhalation valve opens during exhalation to discharge humid air and heat, reducing exhalation resistance and improving comfort during extended use.

Good Fit and Seal

Adjustable internal nose clip combined with a sponge nose pad and wide knitted head strap ensures a tight facial seal to reduce leakage.

Applications

Hot or long-duration work: Summer outdoor work, high-temperature workshops where the valve reduces stuffiness.
High-intensity labor: Construction, material handling where reduced breathing resistance is beneficial.
General industrial dust: Grinding, sweeping, material handling with non-oil particulates.

Frequently Asked Questions

Q: What is the difference between HF0204V and HF0301V?

A: HF0204V has a 4-layer structure while HF0301V has a 5-layer structure. Both are valved, head-strap KN95 respirators, but HF0204V is designed for lighter weight and optimized breathing resistance.

Q: Can valved respirators be used in medical or epidemic settings?

A: Not recommended. The exhalation valve allows unfiltered exhaled air to escape, which could pose a risk to others. Therefore, they are typically prohibited in sterile environments like operating rooms and are not recommended for general public use during epidemics.

Q: Does the valve affect filtration efficiency?

A: No. The valve only opens during exhalation. During inhalation, the valve is closed, and air passes through the filter material. Thus, the valve does not reduce the wearer's protection.

Q: Can this respirator reduce odors?

A: HF0204V is a standard filter model without an activated carbon layer, so it has limited effect on reducing organic vapors or other odors. For odor relief, choose activated carbon models.

Q: How should I maintain the exhalation valve?

A: This is a single-use respirator. Do not disassemble or clean the valve. Replace the entire respirator if the valve is damaged or blocked.
