EP-PF90C PF120C dust filter formaldehyde removal activated carbon filter element

Product Description

EP-PF90C / PF120C Dust Filter Formaldehyde Removal Activated Carbon Filter Element is a premium, dual-function filtration 

component engineered specifically for air purification systems where both particulate removal and chemical gas adsorption 

are required. This innovative filter element combines high-efficiency dust filtration with powerful formaldehyde and volatile

 organic compound (VOC) removal – making it the ideal solution for indoor air quality management in residential, commercial,

 and industrial environments.

EP-PF90C / PF120C Dust Filter Formaldehyde Removal Activated Carbon Filter Element features rigorously selected end caps 

manufactured to exacting dimensional standards, ensuring seamless compatibility with standard air purifier housings and HVAC

 filter slots. The precision-machined end caps provide a secure, leak-free seal that eliminates bypass airflow – guaranteeing

 that all circulating air passes through the active filtration media. The standardized dimensions simplify the installation process,

 significantly reducing downtime during scheduled maintenance intervals and eliminating the need for costly adapters or 

housing modifications.

EP-PF90C / PF120C Dust Filter Formaldehyde Removal Activated Carbon Filter Element is constructed with thickened, 

heavy-gauge PET (polyester) materials that deliver superior structural integrity and pressure resistance. This robust 

construction withstands the demanding operating conditions commonly encountered in air handling systems – including variable 

airflow rates, humidity fluctuations, and temperature changes. The enhanced durability translates directly to extended service life,

 ensuring reliable filtration performance throughout the product's recommended service interval.

EP-PF90C / PF120C Dust Filter Formaldehyde Removal Activated Carbon Filter Element delivers outstanding dual-function

 performance characterized by high dust-holding capacity, low airflow resistance, and exceptional chemical adsorption efficiency. 

Its optimized folded pleat design maximizes effective filtration surface area, while the integrated activated carbon layer provides

 powerful adsorption of formaldehyde, benzene, toluene, and other harmful gaseous pollutants. The balanced design achieves 

an ideal compromise between particulate filtration and gas adsorption – ensuring clean, healthy air without compromising 

system airflow or energy efficiency.

FAQ – Frequently Asked Questions

Q1: What is the difference between EP-PF90C and EP-PF120C?

A1: EP-PF90C / PF120C Dust Filter Formaldehyde Removal Activated Carbon Filter Element are available in two sizes to fit 

different air purifier models. EP-PF90C is designed for compact/medium-sized units, while EP-PF120C fits larger systems.

 Please check your equipment's model number and dimensions to select the correct size.

Q2: How does this filter remove formaldehyde?

A2: The EP-PF90C / PF120C Dust Filter Formaldehyde Removal Activated Carbon Filter Element uses high-quality activated 

carbon impregnated into the filter media. Activated carbon has a vast network of microscopic pores that trap formaldehyde

 molecules through physical adsorption and chemical bonding – permanently removing them from the air stream.

Q3: How long does the activated carbon remain effective?

A3: The activated carbon in the EP-PF90C / PF120C Dust Filter Formaldehyde Removal Activated Carbon Filter Element typically 

remains effective for 3–6 months under normal usage conditions. Effectiveness depends on: (a) hours of operation;

 (b) formaldehyde concentration in the environment; (c) airflow volume. When you notice reduced odor/chemical removal, 

it's time to replace.

Q4: Can the filter be washed and reused?

A4: No, the EP-PF90C / PF120C Dust Filter Formaldehyde Removal Activated Carbon Filter Element is a disposable filter. 

Washing damages the PET media, leaches out the activated carbon, and reduces filtration efficiency. Vacuuming the surface may 

remove loose dust but does not restore chemical adsorption capacity. Replacement is the only recommended practice.

Q5: What is the warranty period?

A5: The EP-PF90C / PF120C Dust Filter Formaldehyde Removal Activated Carbon Filter Element carries a 3-month warranty against

 manufacturing defects in materials and workmanship. The warranty does not cover reduced effectiveness due to normal service

 life expiration or installation in improper conditions.

Q6: What material is the filter made of?

A6: The EP-PF90C / PF120C Dust Filter Formaldehyde Removal Activated Carbon Filter Element uses high-grade PET (polyester)

 substrate with a coating of high-quality activated carbon. The end caps are made from durable PET/paperboard material with

 a foam sealing gasket for leak-proof fit.

Q7: What filtration efficiency does it achieve?

A7: The EP-PF90C / PF120C Dust Filter Formaldehyde Removal Activated Carbon Filter Element achieves ≥99% particle capture 

efficiency for particles ≥0.3μm when used with a pre-filter. Formaldehyde removal efficiency is ≥95% per GB/T 18801 testing 

standards.

Q8: Can this filter remove other VOCs besides formaldehyde?

A8: Yes, the activated carbon in the EP-PF90C / PF120C Dust Filter Formaldehyde Removal Activated Carbon Filter Element also

 adsorbs benzene, toluene, xylene, and other volatile organic compounds (VOCs) commonly found in paints, adhesives, 

cleaning products, and furnishings.

Q9: How do I know when to replace the filter?

A9: Indicators for replacing the EP-PF90C / PF120C Dust Filter Formaldehyde Removal Activated Carbon Filter Element: (a) 

visible dust buildup or darkening of the filter surface; (b) reduced airflow from the purifier; (c) persistent odors or chemical smells; 

(d) 3–6 months of usage; (e) high formaldehyde readings despite purifier operation.

Q10: Is this filter compatible with all air purifiers?

A10: The EP-PF90C / PF120C Dust Filter Formaldehyde Removal Activated Carbon Filter Element is manufactured to fit standard 

purifier housings. However, dimensions vary between brands. Please verify your equipment's filter compartment dimensions 

and model compatibility before ordering.

Q11: What is the recommended operating temperature and humidity?

A11: The EP-PF90C / PF120C Dust Filter Formaldehyde Removal Activated Carbon Filter Element operates effectively from -10°C

 to +50°C with humidity up to 95% RH (non-condensing). Avoid installing in areas with excessive moisture or where water may 

contact the filter.

Q12: How should I store spare filters?

A12: Store the EP-PF90C / PF120C Dust Filter Formaldehyde Removal Activated Carbon Filter Element in a cool, dry, dust-free 

environment away from direct sunlight, moisture, and strong chemical fumes. Keep in original sealed packaging until installation. 

Do not expose to high humidity – this can prematurely saturate the activated carbon.

Q13: What is the disposal method for used filters?

A13: Used EP-PF90C / PF120C Dust Filter Formaldehyde Removal Activated Carbon Filter Element filters should be disposed of 

as general household waste. Do not incinerate, as the activated carbon and PET media may release fumes. Check local regulations

 for specific disposal guidelines.

Q14: Do you offer bulk pricing for commercial customers?

A14: Yes, we offer volume discounts for commercial facilities, property managers, and maintenance service providers. 

Please contact our sales team with your estimated annual consumption for a customized quotation.

Q15: How quickly can I receive replacement filters?

A15: Standard orders for the EP-PF90C / PF120C Dust Filter Formaldehyde Removal Activated Carbon Filter Element ship within

 24–48 hours (domestic) and 3–5 business days (international). For bulk orders, lead time may vary – please confirm with our

 customer service team.

Q16: Can I use this filter without a pre-filter?

A16: The EP-PF90C / PF120C Dust Filter Formaldehyde Removal Activated Carbon Filter Element can be used as a standalone filter, 

but we recommend a coarse pre-filter upstream to capture larger dust particles. This extends the service life of the activated

 carbon layer by preventing premature surface blockage from large particulate matter.
