Product Description

The Airpura C700 DLX is the “abatement plus” configuration of Airpura's chemical and gas line. It keeps the C700 platform — a 26 lb activated carbon bed, 635 CFM (free flow) fan, and a rating of up to 2,500 sq ft per Airpura — and adds Airpura's enhanced carbon program: the DLX performance sheet lists an enhanced impregnated activated carbon bed, with potassium iodide, potassium permanganate, and German carbon blends offered for targeted chemical and odor work.

Who It's For

  • Buyers targeting specific chemicals or stubborn odors that plain coconut shell carbon addresses more slowly
  • Odor-sensitive users — Airpura offers its German carbon option on the DLX specifically for people sensitive to the slight odor new carbon can carry
  • Homes near industrial or agricultural chemical sources, and buildings with long-running off-gassing
  • Workspaces with routine chemical use — salons, studios, workshops
  • Larger spaces up to 2,500 sq ft, per Airpura's rating at 8 ft ceilings and 2 air changes per hour

Key Features

  • 26 lb enhanced carbon bed — 570 sq in of surface area; Airpura's DLX performance sheet lists an enhanced impregnated activated carbon bed
  • Carbon blend options per Airpura — potassium iodide blend, potassium permanganate blend, and a German premium carbon for odor-sensitive users
  • 635 CFM free-flow airflow (450 CFM with filters installed, per Airpura's performance sheet) with 360-degree intake
  • HEPA-barrier post filter — captures 95% of airborne particles at 1 micron and larger per Airpura, and traps carbon dust
  • Quiet low speed — 30.2 dB measured at 6 ft per Airpura, for continuous operation
  • Vacuumable poly prefilter, variable-speed fan, powder-coated steel housing on casters
  • Filtration only — no ozone-producing technology; per Airpura, zero ozone emissions

How the Filtration Works

Air enters 360 degrees around the base and moves through three stages:

  1. Poly prefilter catches dust, lint, and hair before they reach the carbon.
  2. 26 lb enhanced carbon bed adsorbs gases, VOCs, and odor compounds; impregnated blends add oxidizing media that, per Airpura, accelerate the binding of specific chemicals plain carbon captures more slowly.
  3. HEPA-barrier post filter captures 95% of particles at 1 micron and larger per Airpura, including any carbon dust from the bed.

As with all C-series units, the design favors gas-phase capacity over fine-particle efficiency — particle-first buyers should look at Airpura's V-series instead.

C600 vs C700 vs C700 DLX

All three C-series models carry a 26 lb carbon bed; airflow, coverage, and carbon configuration set them apart:

  • Airpura C600 — 560 CFM, rated 2,000 sq ft, 26 lb coconut shell carbon in a 3 in. bed
  • Airpura C700 — 635 CFM, rated 2,500 sq ft, 26 lb coconut shell carbon bed
  • C700 DLX (this model) — 635 CFM, rated 2,500 sq ft, enhanced impregnated carbon configuration with blend options including German carbon

If wildfire smoke is the driver — fine particles plus odor — compare the Airpura V714. For a guided pick, see Which Airpura Is Right for You or browse the Airpura collection.

Filter Replacements

Per Airpura, replace the poly prefilter about every 12 months, the carbon bed about every 24 months, and the HEPA-barrier about every 12 months — sooner under sustained chemical load. The C-series replacement filter bundle covers the stack, and the poly prefilter pack (600/700 series) fits the C700 DLX.

Warranty & Support

Airpura backs the C700 DLX with a 5-year parts and 10-year labor warranty for residential use, per Airpura's published terms.

Frequently Asked Questions

What does the DLX add over the standard C700?

Airflow, coverage, and carbon weight are the same. The DLX is about the carbon itself: Airpura's DLX performance sheet lists an enhanced impregnated activated carbon bed, and the model carries Airpura's blend options — potassium iodide, potassium permanganate, and a German premium carbon aimed at odor-sensitive users. If plain coconut shell carbon covers your needs, the standard C700 does the job.

What is impregnated carbon, in plain terms?

Activated carbon treated with an added compound — such as potassium iodide or potassium permanganate — that chemically reacts with certain gases rather than only physically adsorbing them. Per Airpura, this speeds capture of specific chemicals that untreated carbon takes up more slowly.

How do I know when the carbon is saturated?

Breakthrough odor: smells the unit had been removing return to the room, or outlet air carries a faint odor of collected contaminants. Airpura's guideline is about 24 months of typical use; heavy continuous exposure shortens the interval.

What chemical and VOC sources should I look for at home?

Paints, stains, adhesives, and caulk; off-gassing from new furniture, cabinets, carpet, and flooring; cleaning products and air fresheners; salon, hobby, and workshop chemicals; and fuels or solvents in attached garages. Long-lived sources like these are what a 26 lb carbon bed is sized for.

What does it cost to run? (estimate)

Per Airpura, draw is about 40 watts on low and 120 watts on high, and Airpura publishes roughly $0.27 per day for 24/7 operation on medium speed. At about $0.17 per kWh the full range is approximately $0.16 per day on low to $0.49 per day on high. Estimates — your electric rate applies.

How loud is it at night?

Per Airpura, 30.2 dB on low measured at 6 ft — low enough for bedrooms and continuous overnight operation — rising to 63.0 dB at the full 635 CFM setting.
