Holmes HAP726-U review

  • Reasonable low entry-level price for a 3-stage filtration air purifier.
  • Annual filter replacement cost is on the low side too.
  • Able to operate in dual position.
  • Up to 16 hours of programmable timer setting.
  • Separate filter change indicator for both HEPA and carbon filter.
  • True-HEPA filter works exceptionally well with activated Arm & Hammer Carbon filter.
  • 5 years official Holmes warranty.
  • Below average odor and smoke (chemical) filtration.
  • Auto mode would really come in handy although we could be asking too much given its price tag.
  • Noise level is minimal given its airflow output but there is a slight motor vibration noise throughout all speed.
  • The large Holmes HAP759-NU would be a better buy with only slight bump on price.

Holmes HAP726-U weight
15 lb (6.8 kg)

Boxy in design, Holmes HAP726-U is moderately sized but weight is on the heavy side (inclusive of filters). A small digital screen with buttons surrounding it is located on the left side of the air purifier displaying vital information such as current fan speed, timer. Buttons are clear but could be bigger and better arranged. Due to the shape of Holmes HAP726-U , the air purifier could be placed vertically or horizontally although it will make any big differences anyway. Air vents are located around Holmes HAP726-U to maximize the airflow delivery rate. 5 years warranty comes standard, inside the air cleaner lies the all-important True HEPA filter and a carbon filter that are easily swappable for replacement.

Airflow performance and applicable area

A brilliant 4-stage filtration setup given its price tag, Holmes HAP726-U official room size recommended by Holmes is medium to large rooms but at 24 m2 (256 sq. ft.) coverage, we would reckon small to medium room size would be best suited for optimal purifying. The True HEPA filter will filter 99.97% of airborne pollutants from air and the arm & hammer carbon filter will handle smoke and odors but only to a certain extend.

Final thoughts on Holmes HAP726-U

There are lot things to be like about Holmes HAP726-U, it is well-priced, well-design and well-equipped. If might not have the most attractive design compared with other series models, the good purifying coverage and airflow delivery rate return alone would make this True HEPA Allergen Remover air purifier a bargain not to be missed.

Holmes HAP726-U 3-stage filtration and purifying applicable area is outstanding when go up against allergens, microorganisms.
