Filters — Frequently Asked Questions

How often should I replace my filter?
Follow the product manual or onboard indicator. Typical ranges: air (6–12 months), water (3–12 months or gallons/liters), pre-filters/sediment (1–6 months, depends on water quality), carbon (3–6 months), and steam descaling media per hardness and usage. Heavy use or poor air/water quality shortens intervals.
OEM vs. compatible filters—what’s the difference?
OEM (original) filters are made by the brand and guarantee fit/spec. Compatible options may offer value if they match the required size/material/specification. When in doubt, choose OEM for warranty alignment.
How can I be sure a filter fits my device?
Match the brand + model number and compare filter part number and dimensions. Many product pages list supported models. When available, use the brand’s serial/lookup tools.
Do I need both HEPA and carbon for my air purifier?
HEPA targets particles (dust, pollen, pet dander). Activated carbon targets gases/odors/VOCs. Many units use a combo pack (HEPA + carbon) for complete coverage.
What matters for water filters and ionizers?
Check micron rating, media type (carbon block/ceramic/ion-exchange), flow direction, and change intervals based on liters or months. Pre-filtration improves taste and protects ionizer plates.
Do cold plunge/spa systems need filtration?
Yes—use sediment pre-filters, carbon, or inline cartridges to reduce particulates and help maintain clarity. Replace more frequently with heavy use.
How should I dispose of used filters?
Follow local guidance. Most HEPA/carbon cartridges go in household trash. Some housings are recyclable once media is removed. Do not burn used filters.

Buying Guide: How to Choose the Right Filter

Step 1 — Identify Your Device

  • Find the brand, model, and filter part number on the label or manual.
  • Note whether you need single or multi-stage packs (e.g., HEPA + carbon).

Step 2 — Match the Media

  • Air: True HEPA (H13/H14) for fine particles; activated carbon for odors/VOCs; pre-filters for larger dust.
  • Water: Carbon block/ceramic/sediment for taste/particulates; ion-exchange or specialty media for scale/metals (per device).
  • Hydro/Plunge/Spas: Inline sediment (5–20 μm) and carbon; confirm flow direction and fittings.
  • Steam/Sauna: Descaling media or polyphosphate per heater spec and local hardness.

Step 3 — Check Size & Compatibility

  • Compare dimensions, gasket style, connector type (bayonet/quick-connect/threaded), and flow arrow.

Step 4 — Plan Replacement Intervals

  • Use the months/hours/liters rating or on-device sensor. Shorten intervals for pets, smoke, heavy use, or hard water.

Step 5 — Stock Up & Label

  • Buy 2–3 sets and write the install date on the housing for easy tracking.

🔎 Quick Reference

Filter Type Typical Interval Specs to Check Notes
HEPA (Air) 6–12 months H13/H14 rating, fit Pair with pre-filter & carbon
Carbon (Air) 3–6 months Carbon weight, thickness Odors/VOCs focus
Pre-Filter (Air) 1–3 months (washable) Washable mesh/foam Extend HEPA life
Sediment (Water) 1–6 months Micron (1–20 μm) Protects downstream media
Carbon Block (Water) 3–12 months Flow, chlorine/VOC rating Taste/odor improvement
Ionizer Cartridge 3–12 months / liters OEM spec, plate care Pre-filtration recommended
Steam Descale Media Per hardness/use Media type/volume Protects heaters

Always follow your device’s manual for approved filter types, install steps, flushing, and replacement timing.

Care, Replacement & Shipping

Power down water or air systems before swapping filters. For water cartridges, keep a towel handy, depressurize housings, and flush per instructions to remove carbon fines. Lubricate O-rings with food-grade silicone and avoid overtightening. For air filters, vacuum or rinse washable pre-filters and replace HEPA/carbon on schedule. Most filters ship boxed with tracking; warranties vary by brand and typically cover materials and workmanship for defined terms.
