Which Honeywell Air Purifier Should You Buy? A Breakdown of Their Top Models

Honeywell's air purifiers deliver genuine HEPA filtration at competitive prices, but which model actually suits your space? The HPA300 series stands out as the best all-rounder, balancing coverage up to 500 sq ft with Energy Star efficiency and a competitive price point around £220–£242.

Why Honeywell?

Honeywell has manufactured air treatment and climate control products since 1906, building a reputation for industrial-grade filtration that has migrated to consumer products. Their strength lies in True HEPA certification—not the "HEPA-type" filters competitors use—which captures 99.97% of particles 0.3 microns or larger. This matters: true HEPA is a regulated standard, meaning Honeywell's filters perform consistently across all their models. They also prioritise Energy Star certification, reducing running costs by 20–30% compared to standard purifiers. Their range is deliberately simple—no gimmicks, no smart-home integration—which keeps prices low and reliability high.

Top Picks

Honeywell HPA5300B Insight True HEPA Air Purifier — £26.00 (Open-Box)

Best for budget buyers and small starter spaces. This is an open-box unit, meaning it's been returned or display stock, but includes full warranty coverage. The HPA5300B covers up to 500 sq ft and uses True HEPA filtration with activated carbon layer for odour removal. The "Insight" display shows air quality in real time. Energy Star rated. At £26, it's exceptional value—though stock is limited as it's overstock.

Honeywell HPA300 Series HEPA Extra-Large Room Air Purifier, White — £241.91

Best all-rounder for most homes. Covers spaces up to 500 sq ft with four-stage True HEPA filtration. The white finish blends into living spaces better than black alternatives. Energy Star certified, meaning lower electricity costs over time. Quiet operation at 50 decibels on low speed. This is Honeywell's standard recommendation for medium-to-large rooms.

Honeywell Energy Star True HEPA Console Air Purifier, Black (HPA300COM) — £219.99

Best for aesthetics and darker interiors. Functionally identical to the white HPA300, but the black finish and console design give it a more contemporary look. Same 500 sq ft coverage, True HEPA four-stage filtration, and Energy Star rating. Choose this over the white version only if colour matches your décor—otherwise, buy the cheaper white model and save £22.

What to Look For

• True HEPA certification: Honeywell uses genuine HEPA filters capturing 99.97% of particles ≥0.3 microns. Cheaper brands use "HEPA-type" filters that capture only 85–90%. Non-negotiable if allergies or asthma are a factor.
• Coverage area in square feet: All three models cover 500 sq ft, which suits a large bedroom, open-plan kitchen, or living room. If your space is under 300 sq ft, any of these will over-deliver; if over 700 sq ft, you'll need a larger model.
• Energy Star rating: All Honeywell models listed are Energy Star certified, cutting running costs by roughly £15–25 per year compared to standard purifiers. Over five years, that's £75–125 saved.
• Filter replacement costs: Honeywell replacement filters cost £30–50 and last 6–12 months depending on air quality. Factor this into total cost of ownership, not just purchase price.

The Bottom Line

Buy the Honeywell HPA300 Series in white (£241.91) unless you specifically need a black finish or have found the open-box HPA5300B in stock. The HPA300 delivers true HEPA filtration across 500 sq ft, Energy Star efficiency, and genuine value—Honeywell's engineering justifies the price. If budget is tight and the open-box unit is available, the HPA5300B at £26 is genuinely remarkable, though stock is unpredictable.

Frequently Asked Questions

Is Honeywell good value for money on air purifiers?

Yes. Honeywell uses True HEPA filters (not cheaper "HEPA-type" alternatives), which is a regulated standard ensuring 99.97% particle capture. Energy Star certification saves £15–25 per year in electricity. At £220–£242 for 500 sq ft coverage, they're mid-market priced but outperform cheaper brands in filtration consistency and durability. Open-box units at £26 are exceptional value if you can find them.

How often do Honeywell air purifier filters need replacing?

Honeywell filters typically last 6–12 months depending on local air quality and usage frequency. Running 24/7 in a polluted area requires replacement every 6 months; occasional use in clean air extends it to 12 months. Replacement filters cost £30–50. The company sells universal filters across their range, so you're not locked into expensive proprietary cartridges.

Can you use a Honeywell air purifier in a bedroom?

Yes, all three models run quietly enough for bedrooms. The HPA300 operates at 50 decibels on low speed—quieter than a typical conversation. Higher speeds (3–4) increase noise to 60–65 decibels, which may disturb light sleepers. Use low speed overnight; the 500 sq ft coverage means even a single air change per hour at low speed will purify a bedroom overnight.

What's the difference between the white HPA300 and black HPA300COM?

They're functionally identical—same True HEPA four-stage filtration, 500 sq ft coverage, Energy Star rating, and 50-decibel low speed. The only difference is colour and console-style design on the black model. The white version is £22 cheaper. Buy the black only if it matches your room better; otherwise, save money and choose white.
