Product Description

The Airpura R700 is the everyday model in Airpura's 700 series: a three-stage purifier that runs air through a poly prefilter, an 18 lb activated carbon bed, and a 40 sq ft True HEPA filter rated to capture 99.97% of airborne particles 0.3 microns and larger. The 700-series fan moves 635 CFM in free flow (450 CFM with filters installed, per Airpura's performance sheet), and Airpura rates the unit for spaces up to 2,500 sq ft. The housing is powder-coated steel with a 360° air intake and casters.

Who the R700 Is For

Airpura calls the R700 "the everyday air purifier" because it balances the two main jobs of home air cleaning: the HEPA filter handles particles — dust, pollen, pet dander, smoke particles, mold spores — while the full 18 lb carbon bed adsorbs household odors, VOCs, and chemical vapors. It suits large open living areas, homes with pets, and anyone who wants one unit that covers both particles and odors without choosing a specialty model. If you want a higher-efficiency particle filter, step up to the R714; if particles are your only concern, look at the HEPA-focused I700. Undecided? See Which Airpura Is Right for You.

Key Features

  • 40 sq ft True HEPA filter captures 99.97% of airborne particles 0.3 microns and larger, per Airpura

  • 635 CFM free-flow airflow with variable fan speed control
  • Rated by Airpura for spaces up to 2,500 sq ft (8 ft ceilings, two air changes per hour)
  • Powder-coated steel housing with 360° air intake and caster wheels
  • 115V household power; 40 W on low, 120 W on high
  • No ozone-producing technology — Airpura lists ozone emissions as none

How the Filtration Works

Stage 1 — Poly prefilter. A 570 sq in poly prefilter catches larger dust, lint, and pet hair at the intake; vacuum it through the grill between annual replacements.

Stage 2 — Activated carbon. Air passes through 18 lb of coconut-shell activated carbon in a 2 in deep bed, which adsorbs odor, VOC, and gas molecules that particle filters cannot capture. Airpura also offers an 18 lb impregnated carbon upgrade for enhanced chemical adsorption.

Stage 3 — True HEPA. The 40 sq ft pleated HEPA filter captures 99.97% of airborne particles 0.3 microns and larger before clean air returns to the room through the 360° outlet.

R700 vs R714 vs I700

All three share the 635 CFM 700-series chassis and the 2,500 sq ft rating; they differ in what sits inside. The R700 (this model) pairs a True HEPA filter (99.97%) with the full 18 lb carbon bed — the balanced pick for particles plus odors. The R714 keeps the carbon bed and upgrades to a Super HEPA 14 filter rated 99.99% at 0.3 microns. The I700 drops the bulk carbon bed entirely and uses over 100 sq ft of True HEPA media instead — the particle-first choice, with only an optional carbon weave for light odors.

Filter Replacements

The R-series replacement filter bundle covers the carbon and HEPA stages in one order, and the poly prefilter pack (600/700 series) keeps stage one fresh in between. Airpura's intervals: prefilter about 12 months, carbon about 24 months, HEPA every 3–5 years.

Warranty & Support

Airpura backs the R700 with a 5-year parts warranty and a 10-year labor warranty for residential use (filters and power plugs are consumables and excluded). OffGrid Horizon is a family-owned authorized Airpura dealer, so units purchased here carry the full manufacturer warranty. Call us at (302) 496-3554 with any questions.

Frequently Asked Questions

Does the R700 produce ozone?

No. The R700 uses only mechanical filtration — prefilter, carbon, and HEPA — with no UV lamp, ionizer, or other emitting technology, and Airpura lists its ozone emissions as none.

What does it cost to run 24/7?

Example math: on high the R700 draws 120 W, so 24 hours uses about 2.9 kWh. At $0.17 per kWh that is roughly $0.49 per day, or about $15 per month. On low (40 W) it is about $0.16 per day. Your local rate will change these figures.

Is it quiet enough for a bedroom at night?

Airpura publishes 30.2 dB on low measured at 6 ft, rising to 63.0 dB on high at the full 635 CFM. The variable speed dial lets you set a middle speed for overnight running.

How often do the filters need replacing?

Per Airpura: vacuum the prefilter regularly and replace it about every 12 months, replace the carbon bed about every 24 months, and the HEPA filter every 3–5 years.

Why does the carbon filter matter?

HEPA media captures particles but not gases. Odors, VOCs, and chemical vapors are molecules that pass straight through a particle filter; the 18 lb activated carbon bed adsorbs them. That is the main functional difference between the R700 and the carbon-free I700.

Does it run on US household power?

Yes. The R700 runs on standard 115V outlets — no special wiring needed.

Can I upgrade the filters later?

Yes. The chassis accepts Airpura's Super HEPA 14 filter (99.99% at 0.3 microns) and an impregnated carbon option at replacement time — or start with the R714, which includes the Super HEPA from the factory.
