Will these filters fit my Peterbilt model?

These filters are manufactured to match original form and fit for many Peterbilt model years. They cover a broad list of models from 210 through 579 (select 2013–2024 applications), but you should verify the part number in your vehicle before ordering.

• Replaces part numbers: 5X013817, 5S013817, WP10154, PA5765, AF55832, CAF24024.
• Compatible with many Peterbilt models including 365, 367, 388, 389, 567, 579 and others listed in the product details.
• Confirm fit by matching the OEM part number or comparing filter dimensions.

How effective is the filtration and what does it capture?

The LZXQYMX cabin filter uses a multi-stage media designed to trap common in-cab contaminants. While not a medical device, it helps reduce airborne particles that typically enter the cabin during normal operation, improving perceived air quality and comfort.

• Captures dust, pollen, soot, and larger particulates from incoming air.
• Multi-layer media increases particle retention compared with basic paper filters.
• Helps reduce debris reaching HVAC components, supporting longer equipment life.

How durable are these filters and how often should they be replaced?

Built from materials resistant to oil, water, and heat, these filters are intended for heavy-duty use in commercial trucks. Replacement intervals depend on operating conditions, but following a regular schedule keeps performance consistent.

• Materials designed for resistance to road oils, moisture, and elevated temperatures.
• Typical recommended replacement: roughly every 12–15 months or about 15,000 miles, depending on environment and usage.
• Buying a 4-pack supports scheduled maintenance without last-minute parts runs.

Is installation difficult and what tools are required?

Installation is intended to be simple: each filter is a direct OEM replacement that generally requires no modifications or special tools. Most users can complete the swap with basic familiarity of the cabin access panels.

• Direct-fit design replaces the original filter with no trimming required.
• Access typically through the cabin filter housing—remove the old unit, insert the new one, and reseal the housing.
• Minimal tools needed; refer to the vehicle manual for specific access instructions.

Who is this for: This 4-pack is aimed at Peterbilt owners, fleet managers, and technicians who want a dependable, value-packed replacement option for routine cabin filter service. If you operate in dusty or high-traffic environments, or you prefer to keep spare filters on-hand for scheduled maintenance, this LZXQYMX set provides a robust, cost-effective solution that matches common OEM part numbers and simplifies upkeep.
