H13 ESSENTIAL FILTER

What is the H13 ESSENTIAL FILTER Husqvarna?

The H13 ESSENTIAL FILTER Husqvarna is a genuine Husqvarna replacement air filter that meets the H13 HEPA classification, meaning it is capable of capturing very small airborne particles at a high efficiency. It is specifically designed as an “essential” or primary high‑efficiency filter stage inside Husqvarna dust and slurry air cleaning systems, rather than a generic pre‑filter. This filter is commonly listed under part numbers 546549601 and 546549701, depending on region and supplier.

H13 refers to a HEPA classification defined in European standards as removing approximately 99.95% of particles at the most penetrating particle size, making it appropriate for capturing respirable crystalline silica dust and other hazardous fine particles on professional construction sites. By installing the H13 ESSENTIAL FILTER Husqvarna in a compatible machine, users get a filtration level that supports a safer working environment and helps meet modern dust‑control expectations.

Compatible Husqvarna equipment

The H13 ESSENTIAL FILTER Husqvarna is primarily specified for use in Husqvarna Construction air cleaners, with most retailers and technical listings calling out compatibility with the Husqvarna A 45 air cleaner/air scrubber. The A 45 is a compact professional air cleaner used to control airborne dust in cutting, drilling, grinding, and renovation applications, and the H13 filter is the main HEPA stage within that system.

Some dealers describe this component simply as “AIR FILTER H13 ESSENTIAL – fits A 45,” confirming that the part is tailored to the internal housing and airflow characteristics of the Husqvarna A 45 rather than being a universal HEPA cartridge. When replacing the filter, it is important to match both the Husqvarna model and the correct part number from the machine’s parts breakdown or manual.

Key features and benefits

The H13 ESSENTIAL FILTER Husqvarna offers a number of important features that make it suitable for demanding professional environments:

• High‑efficiency H13 HEPA filtration: Meets the EU definition of HEPA H13 level filtration, which corresponds to about 99.95% capture efficiency under standardized tests at maximum rated airflow. This capability is critical for controlling respirable dust in concrete and masonry work.

• Designed for Husqvarna airflow and housing: The filter is built to match the dimensions, sealing interfaces, and airflow resistance of Husqvarna air cleaners, ensuring that air passes through the media rather than bypassing around it.

• Essential stage in multi‑stage filtration: Husqvarna air cleaners typically use pre‑filters in front of the H13 filter, allowing coarse dust to be captured early and extending the life of the HEPA element. The H13 ESSENTIAL FILTER serves as the final high‑efficiency stage.

• Supports cleaner, safer jobsites: By capturing a high percentage of airborne fine particles, the filter helps reduce dust exposure for workers and occupants, which is particularly important when working with materials that generate silica dust.

• Genuine OEM quality: Sold as a Husqvarna‑branded spare part or through authorized distributors, ensuring predictable performance and fit.

Retailers commonly market the H13 ESSENTIAL FILTER Husqvarna as an upgrade or essential component for maintaining effective dust control, emphasizing its role in improving air quality on interior and enclosed projects.

Technical characteristics and standards

While individual product pages may not list every dimension or media specification, several technical aspects can be understood based on Husqvarna’s documentation and the HEPA H13 standard:

• Filter class: HEPA H13, with a filtration efficiency of 99.95% according to EN 1822‑1 or similar European HEPA standards.

• Application type: Final or essential filter in a two‑ or three‑stage filtration system for air cleaners used with construction dust.

• Part numbers: Frequently sold under 546549601 and 546549701, both described as “H13 ESSENTIAL FILTER” in Husqvarna spare‑parts catalogs and distributor listings.

• System compatibility: Listed explicitly for Husqvarna A 45 air cleaner; some vendors also categorize it broadly as a Husqvarna Construction spare part, indicating use in the air‑cleaning product line rather than garden or forestry tools.

Husqvarna’s own air‑cleaner information explains that its HEPA filters are individually tested and verified to meet their stated class at full airflow, which assures contractors that the H13 ESSENTIAL FILTER maintains performance even under heavy dust load conditions typical of concrete cutting and grinding.

Typical uses and application areas

In practice, the H13 ESSENTIAL FILTER Husqvarna is used in environments where dust control is a regulatory, safety, or cleanliness priority. Common applications include:

• Concrete cutting and grinding: Capturing airborne silica and cement dust generated by floor grinders, saws, and wall chasers to help reduce worker exposure.

• Renovation and remodeling: Filtering fine dust from plaster removal, tile demolition, and drywall sanding in occupied buildings where cleanliness is critical.

• Drilling and coring operations: Supporting general dust reduction when combined with local extraction systems and air cleaners.

• Industrial and commercial maintenance: Providing background air cleaning in workshops or plant areas where fine particulate is a concern.

Husqvarna highlights that using correctly specified HEPA filters in air cleaners is part of a comprehensive strategy to manage dust risks in construction and renovation, complementing point‑of‑source vacuums and wet cutting techniques.

Replacement intervals and maintenance guidance

Suppliers describe the H13 ESSENTIAL FILTER Husqvarna as a replaceable consumable that should be changed when airflow decreases, filter status indicators on the air cleaner show a service requirement, or visual inspection reveals heavy loading or damage. Husqvarna air cleaners may include LED filter‑status bars, leakage warning systems, or HEPA test functions to help determine when the essential filter needs replacement.

Husqvarna also provides general guidance that pre‑filters should be replaced more frequently to protect the H13 stage, which extends the service life and maintains filtration efficiency. The replacement procedure typically involves:

• switching off and unplugging the air cleaner;

• opening the filter compartment according to the machine manual;

• removing the used H13 ESSENTIAL FILTER carefully to avoid releasing trapped dust; and

• installing the new filter with correct orientation and sealing.

Many air‑cleaner training resources stress the importance of using genuine HEPA filters of the correct class and not attempting to clean or blow out H13 filters, since that can damage the media and reduce performance.

Pricing and ordering information

Online distributors list the H13 ESSENTIAL FILTER Husqvarna at professional‑grade price points that reflect its HEPA classification and OEM origin. For example, several retailers show the filter with list or sale prices in the mid‑hundreds of dollars, and note that it is sold individually as a spare part. Product listings generally include:

• the product name “H13 ESSENTIAL FILTER Husqvarna”;

• the Husqvarna part number (such as 546549601 or 546549701); and

• association with the A 45 air scrubber or Husqvarna Construction spare‑parts category.

Contractors are usually advised to keep spare H13 filters in stock to avoid downtime on critical dust‑sensitive projects, especially where air cleanliness is part of project specifications or inspection requirements.

Why choose the H13 ESSENTIAL FILTER Husqvarna?

For professionals searching specifically for “H13 ESSENTIAL FILTER Husqvarna,” several advantages make this component stand out:

• Verified H13 performance: Husqvarna’s HEPA testing practices and compliance with recognized HEPA classifications give confidence that the filter actually delivers the stated performance under real operating conditions.

• Purpose‑built for Husqvarna A 45: Perfect fit and sealing reduce bypass risk and maintain proper airflow, which is crucial for both air cleaning effectiveness and machine reliability.

• Health‑focused design: By capturing hazardous fine dust, the filter supports a healthier work environment and aligns with growing regulatory and client expectations around dust control.
