Buying Guide
Filtration performance
Look for a true HEPA (H13 or H14) filter to capture fine particles such as pollen, pet dander and PM2.5. An activated carbon layer is useful for removing cooking and household odours - check manufacturer test claims rather than marketing buzzwords.
Room size and CADR
Match the purifier's recommended room coverage or CADR (clean air delivery rate) to the room you want to treat - bedrooms, open‑plan living rooms and small flats need different capacities. Under £200 models generally suit bedrooms or medium living rooms rather than large open‑plan spaces.
Noise and fan speeds
Noise matters if you plan to run the unit overnight; look for sleep mode or low decibel ratings and multiple fan speeds. Manufacturers often quote dB(A) on the lowest and highest settings - choose a quieter model for bedrooms and nurseries.
Running costs and filter replacement
Consider how often filters need replacing and their cost - annual filter bills can add significantly to the total ownership cost. Also check the unit's energy use and whether it has an eco or auto mode to reduce running costs.
Controls, smart features and maintenance
Decide if you want simple manual controls or app/Wi‑Fi integration and voice assistant support - smart features add convenience but can push the price up. Also check how easy it is to replace filters and whether the manufacturer provides clear filter life indicators.
Frequently Asked Questions
What is the best air purifier in 2026?
By 2026, for the under‑£200 bracket the top picks remain models that combine a true HEPA filter, useful CADR and low noise. Widely recommended choices include compact units from Levoit (Core series) and Xiaomi (Mi Air Purifier 3H) because they balance filtration performance, quiet running and affordable replacement filters - but always check up‑to‑date reviews and current prices from UK retailers.
Is an air purifier worth buying in the UK?
Yes for many people - they help reduce allergens, fine particulate pollution (PM2.5) and some odours, particularly in city flats or homes with pets. They are not a substitute for proper ventilation or mould remediation, but they can be worthwhile for allergy sufferers and those wanting cleaner indoor air.
Which air purifier offers the best value for money?
Value depends on your needs: for bedrooms a quiet, efficient model with affordable replacement filters is best value; for larger living areas you want higher CADR. In the sub‑£200 range, compact Levoit and Xiaomi models often represent good value in the UK because of strong filtration, low noise and reasonable filter costs.
Levoit vs Xiaomi - which should I buy?
Levoit is often praised for very quiet operation and simple, user‑friendly controls, making it ideal for bedrooms. Xiaomi tends to offer higher airflow and strong smart features (app control) at a similar price - pick Xiaomi for larger rooms or if you want app integration, and Levoit for quieter, straightforward performance.
Where can I buy air purifiers under £200 in the UK?
Major retailers such as Amazon UK, Argos, John Lewis, Currys and AO stock budget and mid‑range models; specialist stores and manufacturer websites also sell them. Watch for seasonal sales (Black Friday, Boxing Day) and check whether the price includes replacement filters.
How large a room can air purifiers under £200 handle?
Most sub‑£200 purifiers are aimed at bedrooms and medium rooms up to roughly 30–40 m², depending on CADR. Always check the manufacturer's recommended room size and aim for a unit that achieves multiple air changes per hour in the room you want to treat.
How often do filters need replacing?
Filter life varies by usage and air quality but expect HEPA and carbon filters to last between 6 and 12 months under typical domestic use. Many manufacturers provide filter life estimates in hours; heavy pollution or running the unit on high continuously will shorten filter life and increase costs.
Will an air purifier get rid of mould or viruses?
Air purifiers with true HEPA filters can capture airborne mould spores and many respiratory aerosols, helping reduce exposure, but they don't remove mould growing on surfaces - that needs cleaning and moisture control. While purifiers can lower airborne virus particles, they are not a replacement for ventilation, vaccination or public‑health measures.
What is the best air purifier for a bedroom under £200 in 2026?
For bedrooms, choose a compact unit with a true HEPA filter and low noise; the Levoit Core series is a strong pick because it typically combines H13 HEPA filtration, very quiet sleep modes and simple controls, making it ideal for overnight use.
Is buying an air purifier under £200 worth it in 2026?
Yes for allergy sufferers or city dwellers - sub‑£200 models with true HEPA filters and activated carbon layers offer meaningful reductions in PM2.5, pollen and odours. They’re most effective when used alongside good ventilation and routine cleaning.
Levoit Core 300 vs Xiaomi Mi Air Purifier 3H - which should I buy?
Choose Levoit Core 300 if you prioritise quieter operation and simple, out‑of‑the‑box use; pick Xiaomi Mi 3H if you need higher airflow for a larger room and want app control and tighter integration with smart home systems. Both provide true HEPA filtration; the decision rests on room size and preference for noise versus smart features.
Which air purifier is best value for money in the UK under £200?
Best value typically comes from models that combine H13 HEPA filtration, an activated carbon layer and low running costs - Xiaomi Mi Air Purifier 3H and Levoit Core models often represent strong value in the UK thanks to their balance of performance, replacement filter availability and competitive pricing.
