Before picking an air filter, first clarify the main air pollution sources in your home—they directly determine the type and performance of the filter you need.
Common household pollutants include:
Fine particles: Dust, pollen, pet dander, and PM2.5 from outdoor air.
Harmful gases: Formaldehyde from new decorations, VOCs from furniture, and kitchen odors.
Microorganisms: Bacteria, mold spores, and viruses that thrive in humid environments.
Special needs: Allergies, asthma, pet ownership, or proximity to busy roads all require targeted filtration solutions.

Whalesens, as a professional air filter manufacturer, offers a full range of products from coarse to high-efficiency HEPA filters, designed to address different household pollution scenarios .
Whalesens filters adopt targeted purification technologies based on pollutant types, ensuring efficient removal while maintaining system performance. Below is the core working principle of main filter types:
Mechanical Filtration (HEPA/Pre-Filter/Medium-Efficiency Filter): Relies on multi-layer fiber structures to block particles through interception, inertial collision, and diffusion. The denser the fiber, the smaller the particles it can capture (e.g., HEPA's ultrafine glass fiber traps 0.3μm particles).
Physical Adsorption (Activated Carbon Filter): High-iodine value activated carbon has abundant porous structures, forming strong adsorption force to lock odors, formaldehyde, and VOCs.
Depth Filtration (Bag Filter): Large surface area and multi-layer bag structure extend the filtration path, achieving high dust-holding capacity without obvious resistance increase.

Filter Type | Efficiency Grade | Particle Removal Size | Key Performance Index | Key Material | Airflow Resistance | Dust-Holding Capacity | Replacement Cycle |
|---|---|---|---|---|---|---|---|
HEPA Filter | H13-H14 | ≥0.3μm | 99.97%-99.99% removal rate | Ultrafine glass fiber | ≤150Pa | 3500g/m² | 6-12 months |
Activated Carbon Filter | Gas adsorption grade | N/A (gases/odors) | Formaldehyde adsorption ≥80% | High-iodine value activated carbon | ≤80Pa | 1200g/m² | 3-6 months |
Pre-Filter | G1-G4 | ≥5μm | Large particle interception | Washable synthetic fiber | ≤50Pa | 6800g/m² | Wash every 1-2 months, replace annually |
Medium-Efficiency Filter | F5-F9/MERV11-15 | 1-5μm | Pollen removal ≥90% | Multi-layer synthetic fiber cotton | ≤120Pa | 4200g/m² | 6-12 months |
HVAC Bag Filter | F6-F9 | 1-5μm | High capacity & durability | Moisture-resistant synthetic fiber | ≤100Pa | 7500g/m² | 12-18 months |
Note: All parameters are tested under standard conditions (airflow velocity 1.5m/s, temperature 25℃, humidity 50%RH). Whalesens products exceed industry standards by 10%-15% in key indicators like dust-holding capacity.

Avoid Over-Purification: For areas with good outdoor air quality (PM2.5 ≤35μg/m³), medium-efficiency F8 filter is sufficient, which is 40% cheaper than HEPA filter but meets daily needs.
Adopt Multi-Stage Filtration: Equip pre-filter + main filter. The pre-filter (≤$10) can extend the main filter's life by 2x, reducing annual replacement cost by 30%. Whalesens "pre + main" combo packs save an additional 15%.
Choose Based on Replacement Cycle: For busy families, select filters with long replacement cycles (e.g., bag filter for 12-18 months) to avoid frequent maintenance; for small apartments, short-cycle filters (3-6 months) are more cost-effective.
Customize for HVAC Compatibility: Ill-fitting filters cause 20% air bypass and reduced efficiency. Whalesens provides free size customization, avoiding waste from mismatched products.
Take Advantage of After-Sales Services: Whalesens offers filter status monitoring (for smart models), reminding replacement on time to avoid efficiency decline due to overuse.
