Primary (pre) air filters G1-G4 protect downstream stages and cut cost. Compare panel, pocket, roll and washable types, with specs and a practical selection checklist.
Medium Filters F5-F9: Pocket, Panel, V-Cell & Selection
Medium-efficiency filters F5-F9 are the workhorses of clean commercial and industrial air. Compare pocket, rigid V-cell and panel builds, with specs and selection tips.
HEPA/ULPA フィルター H10-H14：タイプ、仕様、選定
HEPA and ULPA filters H10-H14 deliver near-total removal of sub-micron particles for cleanrooms, ORs and pharma. Compare mini-pleat, separator and box builds with specs.
初効率 vs 中効率 vs 高効率フィルター：横並び比較
A one-page comparison of primary (G1-G4), medium (F5-F9) and HEPA/ULPA (H10-H14) air filters-efficiency, pressure drop, life, cost and where each belongs.
Air Filter Maintenance: Pressure Drop & When to Replace
Replace filters on pressure drop, not the calendar. Learn to read a differential manometer, set final ΔP limits, and plan safe changeout for primary, medium and HEPA stages.
空氣フィルターの基礎：仕組みと HVAC システムに必要な理由
Air filters trap dust, pollen and microbes from moving air. Learn how filtration works, the key terms-efficiency, pressure drop, dust-holding-and why every HVAC system needs one.
空気フィルター効率クラス：G1-G4、F5-F9、H10-H14
Demystify air-filter ratings-coarse G1-G4, fine F5-F9 and HEPA H10-H14. Understand EN 779, ISO 16890 and EN 1822 so you can specify the right class with confidence.
どの空気フィルターをどこへ：業界・空間別適用ガイド
A practical map of which air-filter class fits which space-offices, hospitals, cleanrooms, paint booths, data centres, food and pharma-plus typical two- and three-stage arrangements.
Choosing Air Filter Material: Fiber, Carbon, Mesh
Filter media is not one material. Compare synthetic fibre, glass fibre, activated carbon and metal mesh on efficiency, temperature, cost and reusability to pick the right media.
SCAC 活性炭フィルターカートリッジ
What Is an SCAC Activated Carbon Filter Cartridge? The SCAC activated charcoal filter cylinder is a modular gas-phase filtration unit for commercial and industrial HVAC systems. It is engineered to strip odours and harmful gases from ventilation air, protecting occupants, equipment and stored collections.
