HEPA filter with wooden frame is a high-end air purification device that combines high-efficiency filtration performance with natural aesthetic design. It is designed for scenes that focus on environmental protection, interior decoration coordination and air quality. It adopts a unique combination of natural wood frame and HEPA high-efficiency filter material, which not only meets the ultra-high efficiency filtration capacity of EN 1822 H13-H14 or ISO 16890 ePM1 99.95% or more, but also gives the device a warm and natural visual texture, making it an ideal choice for high-end residences, art spaces, boutique hotels and sustainable buildings.
Core structure and technical features
Frame material and craftsmanship
Natural wood:
Selected wood: sustainable hardwood such as oak, walnut, bamboo, etc., with natural texture on the surface, suitable for Nordic, Wabi-sabi and other design styles;
Environmental treatment: water-based paint coating or plant oil polishing, zero formaldehyde release, in line with FSC (Forest Stewardship Council) certification.
Moisture-proof reinforcement: wood is carbonized or impregnated with resin at high temperature, mildew-proof and insect-proof, and humidity tolerance is ≤75% RH.
HEPA filter element design
Filter material:
Glass fiber: high temperature resistance (≤250℃), chemical inertness, medical-grade sterility guarantee;
Electret polyester fiber: low-resistance electrostatic adsorption, interception rate of 0.3μm particles ≥99.97% (H13 grade).
Sealing structure: Food-grade silicone or natural rubber sealing strips are used between the filter element and the wooden frame, and the leakage rate is ≤0.01%.

Selection and maintenance guide
Selection points
Design adaptation:
Wood grain and color: match the main indoor materials (such as flooring, furniture), provide customized dyeing services;
Hidden/display: optional embedded installation or independent art installation form
Performance requirements:
High humidity areas (such as next to the bathroom): choose bamboo or carbonized wood frame + mildew filter;
Allergy protection: choose H14 grade filter material + antibacterial coating.
Maintenance strategy
Filter replacement:
Through differential pressure gauge or smart reminder (APP linkage), the recommended threshold is ≤300Pa;
Standard replacement cycle is 12-24 months (can be extended in low pollution environment).
Frame maintenance:
Regularly use wood wax oil for care, avoid direct sunlight or extreme dryness;
Check the mildew prevention status every month in humid environments and wipe off the surface moisture in time.
Industry innovation and trends
Smart IoT: built-in temperature, humidity and PM2.5 sensors, wooden panel LED light strips visualize air quality;
Art customization: cooperate with artists to hand-paint or laser engrave to create limited edition air purification artworks;
Biological-based upgrade: use mycelium composite wood or recycled wood fiber to achieve 100% degradable frame.
The wooden frame HEPA filter redefines the value of air purification equipment with “natural aesthetics, ultimate purification, and timeless design”, becoming a dual endorsement of healthy life and space aesthetics. From private homes to public spaces, it is not only a guardian of the air, but also a concrete expression of modern people’s pursuit of the concept of natural symbiosis.
