Product Overview
The True 14 HEPA Replacement Filter for 240 Air Purifier (2-Pack) is engineered to match the fit and function of the original 240 HP-14 filter. Supplied in packs of two, these cartridges are dimensionally identical to the OEM parts, allowing you to slide them into your purifier housing without any resizing or tilt. Each filter is pre-tested for proper airflow and sealing to ensure consistent performance across multiple units. Whether you own a residential model for allergy relief or a commercial-grade purifier for office use, these replacements promise hassle-free compatibility.
At the core of each filter lies a 3-stage filtration system. The first layer captures large debris such as dust, lint, and pet hair, extending the life of the main HEPA element. The middle stage features a Grade True HEPA medium, trapping 99.97% of particles down to 0.3 microns—this includes pollen, mold spores, and fine smoke particles. The final activated carbon section adsorbs volatile organic compounds (VOCs), cooking odors, and pet smells, making it well-suited for kitchens, smoke-prone areas, and homes with furry companions.
Materials matter: these filters are crafted from FSC-certified paper products, ensuring responsible forestry sourcing. The frame is made of sturdy ABS plastic to withstand repeated insertions and removals without cracking. Pre-packaging tests check each cartridge for quality compliance and particle retention. Once the filter arrives, it’s ready to install—simply unwrap and set it in the machine. No special tools or adapters are required, and the snug fit eliminates any bypass leaks.
Maintenance is straightforward. Under ideal conditions, replace the filter every six months. However, high-pollutant environments may shorten its life. Amazon customers often opt for the Subscribe & Save plan to receive fresh filters automatically. Should you encounter any fitment or performance issues, the manufacturer’s customer service team pledges responsive support and offers a satisfaction guarantee. Overall, this replacement filter is positioned as a cost-effective solution for keeping your 240 air purifier operating at peak efficiency.

Who Should Consider True 14 HEPA Replacement Filter?
Pet owners and urban dwellers facing allergens and odors will benefit most from the activated carbon and True HEPA combo. If you subscribe to a six-month replacement cycle and don’t mind swapping filters twice a year, this is a budget-friendly alternative to OEM parts. However, if you need the filter to run reliably for over three months without change alerts, you might prefer the original brand filters or consider adding a pre-filter layer to extend lifespan. Enrolling in Amazon’s Subscribe & Save program can further reduce cost and ensure you never run out of fresh filters.
- Offers excellent value with OEM-comparable results.
- Plan for regular replacements every 2–6 months.
